Finding and operating on image lists
Updated: June 18, 2019

A major amount of time is spent figuring out how to locate images of interest. Here I describe some software tools I have developed for this, mostly with an eye towards using PAS images.

  2. Three sets of images.

A fast way to find images.

We often want to quickly find the acm or gc image assocuated with some observation made with a primary HET instrument (LRS2, VIRYS, HPF). 


# Find the list of images (example:  last image of gc1) 
% pas_imlistgen l gc1 N 
  7484  1

# Make an easily-read time+image list 
% pas_imlistgen l gc1 N 
  7484  1

% pas_timelist list.IMAGES A N         # I process the list of ALL images 
a 1  Fri Sep 28 14:18:27 UTC 2018
a 2  Fri Sep 28 14:19:03 UTC 2018
36.000000   (aprroximate run time in seconds)

The run above makes a file named "A". This list has 3 quantities 
per line: 
  1  - the line number on the input list (i.e. list.IMAGES) 
  2  - the floating point number of seconds since 0h UT for the night in question 
  3  - fullpath name of the image
The pas_imlistgen code is geared towards locating HET images. To locate the FITS images This code uses the very general code fitsfind.
