Filter Description

Filter ID (?) :UKIRT/WFCAM.K_filter
Description (?) :WFCAM K filter (filter only)
Phot.System (?) :WFCAM
Detector Type (?) :Photon counter
Band Name (?) :------
Obs. Facility (?) :UKIRT
Instrument (?) :WFCAM
Comments (?) :The filter profile here was measured at room temperature and is not
corrected for the wavelength shifts induced by cooling to 120K and
the 10-degree angle of incidence of the beam on the filter. For a
description of the final transmission curve, corrected for detector
quantum efficiency, angle of incidence and the operating temperature
of the filter, please see UKIRT/WFCAM.K.
