SVO Filter Profile Service

Filter ID (?) : XMM/OM.V

Description (?) : XMM OM V filter full effective area

Phot.System (?) : XMM

Detector Type (?) : Photon counter

Band Name (?) : V

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
