Setting source-quality flags

When the parameter mode is set to usequalityimage, the program works as follows:

1. Load the quality map image from the QUALITY fits file extension in the input image file (parameter set).
2. If the input image is a sky-image load the RA and DEC coordinates from the SRCLIST fits table in the input source-list file (parameter srclistset, and convert these coordinates to image x and y coordinates using the CDELT1, CDELT2, CRPIX1, CRPIX2, CRVAL1 and CRVAL2 FITs keywords in the header. otherwise load the x and y coordinates from the SRCLIST fits table in the input source-list file (parameter srclistset.

3. Load the QUALITY flags from the SRCLIST fits table in the input source-list file (parameter srclistset.

4. Set the QUALITY flags of each source (see section 9

5. Create the output file (parameter outset that will store the modified source-list (the output file can have the same name as the input file).
