DESCRIPTION
Calculate principal components through demagnetization data using bounds and calculation type stored in "redo" file
SYNTAX
zeq_magic_redo.py [command line options]
OPTIONS
-h prints help message
-usr USER: identify user, default is ""
-f: specify input file, default is magic_measurements.txt
-F: specify output file, default is zeq_specimens.txt
-fre REDO: specify redo file, default is "zeq_redo"
-fsa SAMPFILE: specify er_samples format file, default is "er_samples.txt"
-A : don't average replicate measurements, default is yes
-crd [s,g,t] :
specify coordinate system [s,g,t] [default is specimen coordinates]
are specimen, geographic, and tilt corrected respectively
NB: you must have a SAMPFILE in this directory to rotate from specimen coordinates
-leg: attaches "Recalculated from original measurements; supercedes published results. " to comment field
INPUTS
zeq_redo format file is:

NAME
kly4s_magic.py
DESCRIPTION
converts files generated by SIO kly4S labview program to MagIC formated
files for use with PmagPy plotting software
SYNTAX
kly4s_magic.py -h [command line options]
OPTIONS
-h: prints the help message and quits
-i: allows interactive input of input/output filenames
-f FILE: specify .ams input file name
-fad AZDIP: specify AZDIP file with orientations, will create er_samples.txt file
-fsa SFILE: specify existing er_samples.txt file with orientation information
-fsp SPFILE: specify existing er_specimens.txt file for appending
-F MFILE: specify magic_measurements output file
-Fa AFILE: specify rmag_anisotropy output file
-ocn ORCON: specify orientation convention: default is #3 below -only with AZDIP file
-usr USER: specify who made the measurements
-loc LOC: specify location name for study
-ins INST: specify instrument used
-spc SPEC: specify number of characters to specify specimen from sample
-ncn NCON: specify naming convention: default is #1 below
DEFAULTS
MFILE: magic_measurements.txt
AFILE: rmag_anisotropy.txt
SPFILE: create new er_specimen.txt file
USER: ""
LOC: "unknown"
INST: "SIO-KLY4S"
SPEC: 1 specimen name is same as sample (if SPEC is 1, sample is all but last character)
NOTES:
Sample naming convention:
[1] XXXXY: where XXXX is an arbitrary length site designation and Y
is the single character sample designation. e.g., TG001a is the
first sample from site TG001. [default]
[2] XXXX-YY: YY sample from site XXXX (XXX, YY of arbitary length)
[3] XXXX.YY: YY sample from site XXXX (XXX, YY of arbitary length)
[4-Z] XXXXYYY: YYY is sample designation with Z characters from site XXX
[5] all others you will have to either customize your
self or e-mail [email protected] for help.
Orientation convention:
[1] Lab arrow azimuth= azimuth; Lab arrow dip=-dip
i.e., dip is degrees from vertical down - the hade [default]
[2] Lab arrow azimuth = azimuth-90; Lab arrow dip = -dip
i.e., azimuth is strike and dip is hade
[3] Lab arrow azimuth = azimuth; Lab arrow dip = dip-90
e.g. dip is degrees from horizontal of drill direction
[4] Lab arrow azimuth = azimuth; Lab arrow dip = dip
[5] Lab arrow azimuth = azimuth; Lab arrow dip = 90-dip
[6] all others you will have to either customize your
self or e-mail [email protected] for help.

NAME
aarm_magic.py
DESCRIPTION
Converts AARM data to best-fit tensor (6 elements plus sigma)
Original program ARMcrunch written to accomodate ARM anisotropy data
collected from 6 axial directions (+X,+Y,+Z,-X,-Y,-Z) using the
off-axis remanence terms to construct the tensor. A better way to
do the anisotropy of ARMs is to use 9,12 or 15 measurements in
the Hext rotational scheme.
SYNTAX
aarm_magic.py [-h][command line options]
OPTIONS
-h prints help message and quits
-usr USER: identify user, default is ""
-f FILE: specify input file, default is aarm_measurements.txt
-crd [s,g,t] specify coordinate system, requires er_samples.txt file
-fsa FILE: specify er_samples.txt file, default is er_samples.txt
-Fa FILE: specify anisotropy output file, default is arm_anisotropy.txt
-Fr FILE: specify results output file, default is aarm_results.txt
INPUT
Input for the present program is a series of baseline, ARM pairs.
The baseline should be the AF demagnetized state (3 axis demag is
preferable) for the following ARM acquisition. The order of the
measurements is:
positions 1,2,3, 6,7,8, 11,12,13 (for 9 positions)
positions 1,2,3,4, 6,7,8,9, 11,12,13,14 (for 12 positions)
positions 1-15 (for 15 positions)
