Set of python codes for SERENDIP 6 ETFITS file analysis

FitsBeamRFI v1 : Basic version. Background copied from analyedFITS.py (Kyle's code). Just made few modification to plot each beam with respect to each other. v2 : Input output of fits file is done with the pyFits, while in the v1 fitsio was used. So structure of the entire program is changed here (active) v3 : With histograms for each beam as stacked histograms to identify RFI lines in the histograms (dropped and not done) v4 : copied from v2, All beams are in a single panel but with different colour

SimulFits.py This prog simulates ETHITS file that I generate using a sample input file. It creates similar file with same length and other parameters. v1 : Basic version with lots of trials, this version is for backup. v2 : More advance vesion with user defined signal and changes v3 : This version has posibility of adding signal in just one beam (Not finished)

analyseFits v1: Basic version I got v2 : Trial with few changes v3 : With color histogram and waterfall diagram and possiblity of bin2frequency, however needs more works to implement Here color represent SNR v4 : With color histogram and waterfall diagram Here color represent Fine Chan number v5 : Copied from v4, this version has choice of SNR range selection to be plotted in the data v6 : Copied from v5, along with the hits histogram, It also plots expected noise distribution from a given number of hits and number of channels

compBeam.py

v1 : Basic version but there a bug, just copied it for backup v2 : Working version. It removes hits present in more than one beam. Although, fits headers are not yet fixed v3 : This version does RFI removal from near by frequency channels across all beams (working version it does remove things which are present near to each other across different beams) v4 : This version does RFI removal in time and fixed corase channel which are known to show fixed RFI lines (done but does not remove in time) v5 : This version will remove RFI lines if they present at different RA and DEC level (test version but not used) v6 : copied from v5, This version will remove RFI averaging over time (failed) v7 : again copied from v5 as the completely different logic was tried. This is the real version which works very well. (active) v8 : Same as v7 but only things now it needs to do is to take command line input for length of the time and frequency window
