ds9_imstats
Updated: July 12, 2019

An easy way to display images, compute statistics in user-specified image regions, and prepare input table files for codes like xyplotter_auto.


% ds9_imstats --help 
% ds9_imstats B.fits Y  

Usage: ds9_imstats a.fits Y 
arg1 - FITS image name 
arg2 - run in interactive mode (Y/N)

This is a fairly simple wrapper code that calls many routines that perform a wide variety of tasks.

July2019: A markII version? In Juyl 2019 I took on a project to measure the plate scale on the guide probe cameras of the HET. One phase of this involves measuring the same star image(s) on different images for the purpose of deriving mean positions with errors. In looking at this I realized that ds9_imstats is set up for some aspects of this. However, here are some useful upgrades that would really enhance this analysis:


1. Store the *.info and *.reg files in a local_red directory. 
2) Produce a basename table file (from midodata.2) that is 
   stored in the local_red directory. 
3) Have a means of invoking the verbose/query mode 
4) Incorporate the use of a mask if desired (this is a mido.sh issue really)

There are other thoughts, but these are starters for now. Actually some (most ?) of these should be done outside of ds9_imstats, but this is the place where most of my thoughts started, so I document initial work here. Because the present code is buried in other scripts, I'll begin by establishng ds9_imstats_markII so that I can freely make upgrades. Not the I have the code ds9_imstats_run that runs this code on a list of image. I really should have stuck with my convention of using "fitslist" instead of "run". So, I'll build a ds9_imstats_markII_fitslist that runs ds9_imstats_markII. This way I can develop aspects of the above wish list in either script without dear of hosing up something in another script.


% ds9_imstats_markII --help 

Usage: ds9_imstats_markII ./S/20190711T040815.4_acm_sci.fits zscale n N 
arg1 - FITS image name 
arg2 - z1 for scaling (can be "q" for query, zscale, or minmax) 
arg3 - z2 for scaling (can be "n" for none) 
arg4 - run in verbose/debug mode? (Y/N) 

Examples: 
  ds9_imstats_markII ./S/20190711T040815.4_acm_sci.fits minmax n N
  ds9_imstats_markII /media/sco/DataDisk1/sco/AD/HET_work/acm_nights/20190711/gc2/20190711T040819.9_gc2_sci.fits 1 5000 N
