Each image fits file (pobjXXX.fits) has 8 extensions, each corresponding to one of the 8 CCDs in the mosaic instrument. From these images, two data products are created: the single-filter object catalogues, containing the positions, fluxes etc. of all sources on the respective detectors. These single-filter catalogues are then combined to create merged 3-filter catalogues, where pointers are incorporated to point back to the original single-filter catalogue positions. The file 'mosaicobs.dat' gives an overview of which field corresponds to which catalogue file. Below is a description of the entries in both sets of catalogues. Indicated between square brackets are the units (if applicable). (12 data files).
