Filter Description

Filter ID (?) :XMM/OM.UVW2
Description (?) :XMM OM UVW2 filter full effective area
Phot.System (?) :XMM
Detector Type (?) :Photon counter
Band Name (?) :UVW2
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
