In February 2002 the IRCAM filter population was stripped down in order to populate the UIST filter wheels (see the UIST web page ). In August 2002 IRCAM was retired from service. All the broad band filters were available in 2002 but the narrowband thermal set was decreased. Also please note that the status of the 3.1 micron ice filter was unclear. The 2002 filter set is listed in the Table below. The new Mauna Kea consortium filters have been installed in all UKIRT cameras; these are identified in the Table as '98(MK)'.
