MOPEX Online Manual

Input List Files

The data, uncertainty, status mask, and outlier mask image files are input into MOPEX via ASCII text files, containing one image filename per line. You will need to make a separate list file for each of the input image types, and the filenames must be in the same order in each of the input lists (i.e. the first filename in the list of image files must correspond to the first filename in the list of uncertainty files and the list of status mask files). As a rule, we recommend always including the full path name of the image files in the input lists, e.g., the list of data files, InputImageList.txt, should look something like this:

/home/joe/data/IRAC/ch1/bcd/SPITZER_I1_5504256_0001_0000_4_bcd.fits
/home/joe/data/IRAC/ch1/bcd/SPITZER_I1_5504256_0002_0000_4_bcd.fits
/home/joe/data/IRAC/ch1/bcd/SPITZER_I1_5504256_0003_0000_4_bcd.fits
etc......

If the full path is not specified, MOPEX will assume that you are specifying a path relative to the working directory.

As an example, to create the input lists for IRAC channel 1 data, in Unix (Solaris/Linux/Mac), one could do:

unix% ls /full/path/to/your/data/*bcd.fits > InputImageList.txt
unix% ls /full/path/to/your/data/*bunc.fits > InputUncList.txt
unix% ls /full/path/to/your/data/*bimsk.fits > InputMskList.txt

The input lists can either be read into MOPEX from the command line by following the syntax described on the pipeline introduction pages (e.g. Overlap or Mosaic), or set in the Namelist file. If you are using the GUI, you can specify the input files in the Initial Settings module. The input file format is identical for both versions of MOPEX.

The default location for the input files is in <working_dir>. When specifying input files, you should use either the full path name or the path relative to the working directory. Calibration files (e.g. PRF files and PMasks) are assumed by MOPEX to be in the cal/ subdirectory of the current working directory.
