# Single Epoch Catalogues in FITS format obtained from SExtractor dual image mode run on PAUS simulated images (*sim.detect.del_edge.sexcat).
# Source detection is performed using COSMOS Subaru simulated images.
# Sources which are less than 200 pixels from edges of each image are removed.
# Photometric zero-points and seeing FWHM for SExtractor runs are taken from the PAUdm using the information of
# the exposure number + ccd number (production ID 680).
# Catalogue filenames have the same structure of reduced images filenames.
# We also include the input UFig catalogues (*gal.cat) for each image.
