On July 1st, 2021 the two-component SCUBA-2 beam profile parameters were updated in accordance with the results published by Mairs et al 2021. This caused a change in the Matched Filter post-processing.
When using a Stardev installation post-July 1st, 2021, executing the matched-filter method is expected to increase the measured peak fluxes of bright point sources by ~15% relative to older versions of Starlink. A similar factor may apply to faint point sources in otherwise “blank fields” but this requires further testing.
