Data Reduction Frequently Asked Questions

How can I inspect the data with IRAF?

The VIRCAM data are multi-extension FITS files, with 16 extensions, one for each detector array. In IRAF the extensions must be displayer/inspected individually. For example:
    display VIRCAM_file_name.fits[4] 1
    imexam VIRCAM_file_name.fits[10]
