| 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.
