procedure are not known, but the scan was made at ambient temperature. A
small shift to the blue will be effected at operating temperature (see
Shift with temperature plot).
Z-band filter manufactured at NDC IR Engingeering according to specifications,
which were set to be as identical to the UKIRT/WFCAM Z-band as possible.
Purchased in 2010.
Certificate of Conformance.
NB! This filter has a strong red leak well beyond the K-filter
wavelength range, i.e. beyond 2.4 microns, giving rise to a high background
dominated by thermal emission.
