The AB Magnitude system [36] has been implemented for OM. The general reprocessing pipeline products and SAS output files contain AB values for all detected sources. This is done by the omsrclistcomb, and the results are written in the OBSMLI source file as AB magnitudes in all filters.
In addition to the absolute flux conversion based on white dwarfs described in § 6.7.2, SAS computes a conversion from AB magnitudes to flux units whose results are also written in the OBSMLI combined source file for all filters.
