    NAME
       revtest_MM1990.py

    DESCRIPTION
       calculates Watson's V statistic from input files through Monte Carlo simulation in order to test whether normal and reversed populations could have been drawn from a common mean (equivalent to watsonV.py). Also provides the critical angle between the two sample mean directions and the corresponding McFadden and McElhinny (1990) classification.

    INPUT FORMAT
       takes dec/inc as first two columns in two space delimited files (one file for normal directions, one file for reversed directions).

    SYNTAX
       revtest_MM1990.py [command line options]

    OPTIONS
        -h prints help message and quits
        -f FILE
        -f2 FILE
        -P  (don't plot the Watson V cdf)

    OUTPUT
        Watson's V between the two populations and the Monte Carlo Critical Value Vc.
        M&M1990 angle, critical angle and classification
        Plot of Watson's V CDF from Monte Carlo simulation (red line), V is solid and Vc is dashed.

        eqarea_magic.py [command line options]

    INPUT
       takes magic formatted sites, samples, specimens, or measurements

    OPTIONS
        -h prints help message and quits
        -f FILE: specify input magic format file from magic, default='sites.txt'
         supported types=[measurements, specimens, samples, sites]
        -fsp FILE: specify specimen file name, (required if you want to plot measurements by sample)
                default='specimens.txt'
        -fsa FILE: specify sample file name, (required if you want to plot specimens by site)
                default='samples.txt'
        -fsi FILE: specify site file name, default='sites.txt'

        -obj OBJ: specify  level of plot  [all, sit, sam, spc], default is all
        -crd [s,g,t]: specify coordinate system, [s]pecimen, [g]eographic, [t]ilt adjusted
                default is geographic, unspecified assumed geographic
        -fmt [svg,png,jpg] format for output plots
        -ell [F,K,B,Be,Bv] plot Fisher, Kent, Bingham, Bootstrap ellipses or Boostrap eigenvectors
        -c plot as colour contour
        -sav save plot and quit quietly

    OUTPUT 
        figures:
            ALL:  numbers refer to temperature steps in command line window
            1) Arai plot:  closed circles are zero-field first/infield
                           open circles are infield first/zero-field
                           triangles are pTRM checks
                           squares are pTRM tail checks
                           VDS is vector difference sum
                           diamonds are bounds for interpretation
            2) Zijderveld plot:  closed (open) symbols are X-Y (X-Z) planes
                                 X rotated to NRM direction
            3) (De/Re)Magnetization diagram:
                           circles are NRM remaining
                           squares are pTRM gained
        command line window:
            list is: temperature step numbers, power (J), Dec, Inc, Int (units of magic_measuements)
                     list of possible commands: type letter followed by return to select option
                     saving of plots creates .svg format files with specimen_name, plot type as name

    NAME
       foldtest.py

    DESCRIPTION
       does a fold test (Tauxe, 2010) on data

    INPUT FORMAT
       dec inc dip_direction dip

    SYNTAX
       foldtest.py [command line options]

    OPTIONS
        -h prints help message and quits
        -f FILE file with input data
        -F FILE for confidence bounds on fold test
        -u ANGLE (circular standard deviation) for uncertainty on bedding poles
        -b MIN MAX bounds for quick search of percent untilting [default is -10 to 150%]
        -n NB  number of bootstrap samples [default is 1000]
        -fmt FMT, specify format - default is svg
        -sav  save figures and quit
    INPUT FILE
	Dec Inc Dip_Direction Dip  in space delimited file

    OUTPUT PLOTS
        Geographic: is an equal area projection of the input data in
                    original coordinates
        Stratigraphic: is an equal area projection of the input data in
                    tilt adjusted coordinates
        % Untilting: The dashed (red) curves are representative plots of
                    maximum eigenvalue (tau_1) as a function of untilting
                    The solid line is the cumulative distribution of the
                    % Untilting required to maximize tau for all the
                    bootstrapped data sets.  The dashed vertical lines
                    are 95% confidence bounds on the % untilting that yields
                   the most clustered result (maximum tau_1).
        Command line: prints out the bootstrapped iterations and
                   finally the confidence bounds on optimum untilting.
        If the 95% conf bounds include 0, then a post-tilt magnetization is indicated
        If the 95% conf bounds include 100, then a pre-tilt magnetization is indicated
        If the 95% conf bounds exclude both 0 and 100, syn-tilt magnetization is
                possible as is vertical axis rotation or other pathologies
        Geographic: is an equal area projection of the input data in

       The output file has the % untilting within the 95% confidence bounds

    NAME
        find_EI.py

    DESCRIPTION
        Applies series of assumed flattening factor and "unsquishes" inclinations assuming tangent function.
        Finds flattening factor that gives elongation/inclination pair consistent with TK03.
        Finds bootstrap confidence bounds

    SYNTAX
        find_EI.py [command line options]

    OPTIONS
        -h prints help message and quits
        -f FILE specify input file name
        -nb N specify number of bootstraps - the more the better, but slower!, default is 1000
        -sc uses a "site-level" correction to a Fisherian distribution instead
            of a "study-level" correction to a TK03-consistent distribution.
            Note that many directions (~ 100) are needed for this correction to be reliable.
        -fmt [svg,png,eps,pdf..] change plot format, default is svg
        -sav  saves the figures and quits

    INPUT
        dec/inc pairs, delimited with space or tabs

    OUTPUT
        four plots:  1) equal area plot of original directions
                      2) Elongation/inclination pairs as a function of f,  data plus 25 bootstrap samples
                      3) Cumulative distribution of bootstrapped optimal inclinations plus uncertainties.
                         Estimate from original data set plotted as solid line
                      4) Orientation of principle direction through unflattening
    NOTE: If distribution does not have a solution, plot labeled: Pathological.  Some bootstrap samples may have
       valid solutions and those are plotted in the CDFs and E/I plot.

    NAME
       foldtest.py

    DESCRIPTION
       does a fold test (Tauxe, 2010) on data

    INPUT FORMAT
       dec inc dip_direction dip

    SYNTAX
       foldtest.py [command line options]

    OPTIONS
        -h prints help message and quits
        -f FILE file with input data
        -F FILE for confidence bounds on fold test
        -u ANGLE (circular standard deviation) for uncertainty on bedding poles
        -b MIN MAX bounds for quick search of percent untilting [default is -10 to 150%]
        -n NB  number of bootstrap samples [default is 1000]
        -fmt FMT, specify format - default is svg
        -sav  save figures and quit
    INPUT FILE
	Dec Inc Dip_Direction Dip  in space delimited file

    OUTPUT PLOTS
        Geographic: is an equal area projection of the input data in
                    original coordinates
        Stratigraphic: is an equal area projection of the input data in
                    tilt adjusted coordinates
        % Untilting: The dashed (red) curves are representative plots of
                    maximum eigenvalue (tau_1) as a function of untilting
                    The solid line is the cumulative distribution of the
                    % Untilting required to maximize tau for all the
                    bootstrapped data sets.  The dashed vertical lines
                    are 95% confidence bounds on the % untilting that yields
                   the most clustered result (maximum tau_1).
        Command line: prints out the bootstrapped iterations and
                   finally the confidence bounds on optimum untilting.
        If the 95% conf bounds include 0, then a post-tilt magnetization is indicated
        If the 95% conf bounds include 100, then a pre-tilt magnetization is indicated
        If the 95% conf bounds exclude both 0 and 100, syn-tilt magnetization is
                possible as is vertical axis rotation or other pathologies
        Geographic: is an equal area projection of the input data in

    OPTIONAL OUTPUT FILE:
       The output file has the % untilting within the 95% confidence bounds
nd the number of bootstrap samples

    NAME
        thellier_magic.py
    
    DESCRIPTION
        plots Thellier-Thellier, allowing interactive setting of bounds
        and customizing of selection criteria.  Saves and reads interpretations
        from a pmag_specimen formatted table, default: thellier_specimens.txt

    SYNTAX 
        thellier_magic.py [command line options]

    OPTIONS
        -h prints help message and quits
        -f MEAS, set magic_measurements input file
        -fsp PRIOR, set pmag_specimen prior interpretations file
        -fan ANIS, set rmag_anisotropy file for doing the anisotropy corrections
        -fcr CRIT, set criteria file for grading.  
        -fmt [svg,png,jpg], format for images - default is svg
        -sav,  saves plots with out review (default format)
        -spc SPEC, plots single specimen SPEC, saves plot with specified format
            with optional -b bounds adn quits
        -b BEG END: sets  bounds for calculation
           BEG: starting step for slope calculation
           END: ending step for slope calculation
        -z use only z component difference for pTRM calculation
        
    DEFAULTS
        MEAS: magic_measurements.txt
        REDO: thellier_redo
        CRIT: NONE
        PRIOR: NONE
  
    OUTPUT 
        figures:
            ALL:  numbers refer to temperature steps in command line window
            1) Arai plot:  closed circles are zero-field first/infield
                           open circles are infield first/zero-field
                           triangles are pTRM checks
                           squares are pTRM tail checks
                           VDS is vector difference sum
                           diamonds are bounds for interpretation
            2) Zijderveld plot:  closed (open) symbols are X-Y (X-Z) planes
                                 X rotated to NRM direction
            3) (De/Re)Magnetization diagram:
                           circles are NRM remaining
                           squares are pTRM gained
            4) equal area projections:
 			   green triangles are pTRM gained direction
                           red (purple) circles are lower(upper) hemisphere of ZI step directions 
                           blue (cyan) squares are lower(upper) hemisphere IZ step directions 
            5) Optional:  TRM acquisition
            6) Optional: TDS normalization
        command line window:
            list is: temperature step numbers, temperatures (C), Dec, Inc, Int (units of magic_measuements)
                     list of possible commands: type letter followed by return to select option
                     saving of plots creates .svg format files with specimen_name, plot type as name

    NAME
        zeq_magic.py

    DESCRIPTION
        reads in magic_measurements formatted file, makes plots of remanence decay
        during demagnetization experiments.  Reads in prior interpretations saved in
        a pmag_specimens formatted file [and  allows re-interpretations of best-fit lines
        and planes and saves (revised or new) interpretations in a pmag_specimens file.
        interpretations are saved in the coordinate system used. Also allows judicious editting of
        measurements to eliminate "bad" measurements.  These are marked as such in the magic_measurements
        input file.  they are NOT deleted, just ignored. ] Bracketed part not yet implemented
