SVO Filter Profile Service

Filter ID (?) : Liverpool/IOI.H_ori

Description (?) : IO:I H filter (bench measure)

Phot.System (?) : ------

Detector Type (?) : Photon counter

Band Name (?) : H

Obs. Facility (?) : LT

Instrument (?) : IO:I

Comments (?) : Transmission curve has been measured in the lab on the bench.
These data were obtained by the manufacturer at a temperature of 300K. In the
cryostat at operating temperature the transmission curve is shifted slightly to the
blue compared to the data presented here.
