| Phot.System (?) : | XMM |
| Detector Type (?) : | Photon counter |
| Band Name (?) : | UVM2 |
| Obs. Facility (?) : | XMM |
| Instrument (?) : | OM |
| Comments (?) : | Filter effective area including the entire telescope response based on inflight measurements.
Take into account that there is a time-dependent, and filter-dependent decline in sensitivity for the OM since launch (which reaches as much as ~20% (in 2019) in the V and furthest UV bands), and that the filter effective areas provided reflect the case at approximately mission start, so any computation of expected output in the OM at a given epoch after mission start, should take these degradation factors into account. The current document describing the degradation is available at
