Note that a lot of my development runs here wer in:
/home/sco/ACM_work_Sep2019  
The night of 20190724 was when I finally got  a good set of offset data for deriving the 
HET guide camera (gc) plate scales.  

 

The fundamental list of images we use is usually the full listing of the PAS images in the data directory specified by the (BaseDir,Date) files. For instance, after a run of acm_table_markII, as shown above, we'll have a file listing the paths to the original (raw) acm images called "list.IMAGES_OLD". Later in the reduction, we might want to view the processed versions of these images. The routines image_process_list and image_fullpath_list can be used for accomplishing this. One prohibitive factor for image_process_list is that ONLY images that do not have versions in the target directory end up in the LIST.IN and LIST.OUT files. In the example below, I show how we can view the processed versions of the acm image we prepares in the previous section.

A general-purpose approach we can use follows:

% cp ACMDAT.images ACMDAT.images_raw 
% image_fullpath_list ACMDAT.images FIXUP newlist.images N  
% mv newlist.images ACMDAT.images 
% point_selector ACMDAT uthrs im N  

Usage: image_fullpath_list list.in FIXUP list.out N 
arg1 - Name of FITS image list (should full path)
arg2 - name of process we are preparing for 
arg3 - name of output file listing referenced images in the process subdirectoy 
arg4 - run in debug mode (Y/N)

The output files of interest are: 
 newlist.images           = images with names for the process subdiretory
 newlist.images_version2  = same as above, except original name used if image does not exist in process subdirectory
 FITS.BaseNames           = a listing of the image basenames

 

Sometimes we want to review a set of images in a interval of UT time. The select_pas_images_by_time can be used for this. This takes as input the ACMDAT table we have already created. However, if no table is present, it will build one on the fly. This way we can make multiple runs with different time intervals in a very efficient manner. Note that in the example below I do not have to be in a ceratin directory, I just have to have the local table file (ACMDAT) present.

% ls 
ACMDAT.images  ACMDAT.images_raw  ACMDAT.params  ACMDAT.parlab	ACMDAT.table
% select_pas_images_by_time ACMDAT.images ACMDAT 07:02:22 07:04:32 START N   
% ls 
ACMDAT.images	   ACMDAT.params  ACMDAT.table	START.params  START.table
ACMDAT.images_raw  ACMDAT.parlab  START.images	START.parlab
% point_selector START uthrs im N  
% bigds9 START.images 1 8
