I use four primary codes for installing WCS into FITS image headers. incorporate four wcsf_ codes. Here I show quick examples of how to use this codes.m

----------------------------------------------------------------------------
Step 1 - Get a rough wcs zeropoint 
  % cat list.Most_Current
   ./local_red/FIXUP/20190217T122456.6_acm_sci.fits
  % wcsf_rough list.Most_Current N
----------------------------------------------------------------------------

----------------------------------------------------------------------------
Step 2 - Confirm the wcs is approximately correct 
  % cat list.Most_Current
    ./local_red/ROUGHWCS/20190217T122456.6_acm_sci.fits

 NOTE: Unless a local version of the image is present at run time, this 
       routine will process the version from ROUGHWCS and deposit the 
       new version(s) into VISCAT. 

  % wcsf_viscat list.Most_Current N

The purpose here is to see the roughly calibrated image with USNO-B1.0 
stars overplotted. If most of the plotted sources lie on top of detected 
stars in our acm image, then we have confirmed the validity of our rough 
WCS solution. 

At thsi stage, our current image is in: 
  ./local_red/VISCAT/20190217T122456.6_acm_sci.fits

Finally, it is worth noting that the USNO catalog for this image and a png 
image file of the field are also in this archival subdirectory. 
----------------------------------------------------------------------------

----------------------------------------------------------------------------
Step 3 - Create an image catalog.

First, we want to specify that we'll use the viscat version of the 
as input to the moments catalog code: 
   % cat list.wcs0
      ./local_red/FIXUP/20190217T122456.6_acm_sci.fits
   % image_fullpath_list list.wcs0 VISCAT list.wcs1 N  
   % cat list.wcs1
      /home/sco/tmp1/w1/local_red/VISCAT/20190217T122456.6_acm_sci.fits
Then we run the catalog code: 
   % wcsf_imgcat list.wcs1 N
----------------------------------------------------------------------------

----------------------------------------------------------------------------
Step 4 -  Make the final fit 
 % cat list.Most_Current
  ./local_red/FIXUP/20190217T122456.6_acm_sci.fits

  % wcsf_final list.wcs1 Y N

Note:
   The input image and the initial detection catalog are taken from 
   the IMGCAT0 archive. The user may elect to build a fresh CDFP 
   catalog of USNO-B1.0 sources, or a pre-existing version from the 
   VISCAT archive is extracted.

The final calibrated image is: ./local_red/WCS/20190217T122456.6_acm_sci.fits
