Detailed description of the data product¶
This Data Product describes the NIR source catalogue created from a NIR stacked frame. The XML file references to a FITS file containing the source catalogue in LDAC format. Currently a Kron elliptical aperture photometry is used to estimate fluxes in units of microJy and AB magnitudes. The list of current parameters included in the catalogue is reported below.
