The SCUBA-2 beam has a broad error beam. As the size of the annulus changes, the contribution from the error beam scales according to the curve-of-growth—see Figure G.1. To correct for an aperture size differing from 60-arcsec diameter you should read off the appropriate scaling factor for your FCF from the graph below.
