SETUP performs a first check of the data related to a common generic name9, and reports on possible consistency problems if mosaics or short-spacing data. Short-spacing tables to be merged with interferometric data are supposed to have the same generic name with the extension tab. For mosaics, all the fields must keep a common generic name followed by -i for each field i; just the generic name should be then specified in the imaging procedures. From this initial inspection of the data, map and pixel sizes are recommended and later used by default in the imaging process.
