_CREATE_IMAGE_CATALOGUE_

source extraction and photometry on all sources

Description:

For the group file, find all the sources and calculate the flux of each detected source. Write the results to a catalogue file. The resulting catalogue file is in FITS_1.0 format with columns defined to produce an LCOGT Standard Catalogue Product.

Notes:

Currently uses SEXTRACTOR for source extraction and for photometry.
The output catalogue is not completely in LCOGT Standard Catalogue Product form and requires post-processing by timecorrect.py in order to propogate the image headers, calculate the missing AIRMASS and TCORR columns and splitting the FLUX_APER and FLUXERR_APER 2D arrays into 8 separate columns.

Required Perl Modules

Starlink::Extractor.
