PAGA statnds for Process A Group of Acm images. This code allows one to efficiently process (header repair, bias and dark subtraction) raw acm images that are listed ina table file. The basename of the table file serves as the first input arguemnt to this script. We usually use the acm_table_markII routine to build this table file. The processed images are deposited in the ./local_red/FIXUP subdirectory.

For a more detiled description see:
%  paga --help 

Usage: paga newacm N  
arg1 - basename of table file (usually ACMDAT or newcam) 
arg2 - run in debug/verbose mode 

The acm FITS headers are adjusted by papa using acm_hdfix_list_markII. See this link for what new header cards are installed for acm images.
