Description

Calibration observations involving single-filtergram intensity measurements to monitor formation of “ice” on the CCD detector.

Coverage / Duty Cycle

These observations were taken only occasionally (approximately monthly) as part of instrument calibration sequences. The number of observations (record counts only) during each mission phase are as follows:

	<1996.04.20	1996.04.20 – 1996.05.22	1996.05.23 – 1998.06.24	1998.10.20 – 1998.12.21	1999.02.03 – 2010.09.14	2010.09.14 – 2011.04.12	>2011.04.12
Partial	0	177	3029	529	25412	1273	0
Complete	0	176	2789	477	24992	1265	0

Superseded records: 0 in addition to 30420 valid
