Initial CCD processing.
Last updated: Mar13,2019

A simple recispe for reducing three nights is given below.



# Specify where the raw data are stored and which night are to be processed 
% cat BaseDir
/home/sco/AD/HET_work/acm_nights

% cat head -5 list.Dates
20170903
20180402
20190219

% acm_BigRed list.Dates N N 
arg1 - Name of file with list of UT dates to be processed
arg2 - Allow interactive query of user (Y/N)
arg3 - run in verbose/debug mode

After the acm_BigRed has completed the run, then your processed images will reside in the current working directory in subdirectories named for each UT night processed.

% ls
20170903/ 20180402/ 20190219/ BaseDir list.Dates
ACM.images  ACM.parlab  ACM.table
list.IMAGES Mean.BIAS list.BIAS list.DARK list.OPEN 

Inside each date subdirectory are the processed images , for example: 
% pwd
/home/sco/ACM_BIAS_STUDY/reds5/20190219/local_red
% ls
FIXUP/	HDFIX/

HDFIX  = images with cleaned and augmented image headers 
HDFIX  = bias (including FBP) and dark frame corrected images
 
As the pipeline progresses other subdirectories will appear.



An example of before- and after- CCD-processing.
