Description

These are calibration data in which filtergrams at each of several different tuning positions taken in quick succession over short time spans are available. The filtergrams are in either full-disc or high-resolution image mode, sampled once every 4 seconds and extracted into 256*256 subrasters on the camera.

The data are acquired occasionally (typically for several hours once every week or so, but sometimes more frequently and for longer intervals) as part of certain targeted campaigns:

1996.10.21, 12.03–04
1999.10.11–15
2000.02.12, 05.15–24, 11.02–06
2001.01.09 – 02.27, 06.08 – 07.09, 09.21 – 11.29
2002.06.13 – 08.16
2005.01.13, 02.04–06, 02.11–17, 04.08–14, 05.06, 08.30, 11.17–20, 12.02–03
2006.03.21, 06.26, 07.28–31
2007.02.06, 03.08, 03.20–28, 04.25, 05.07, 05.23
2010.07.01, 08.06–13, 08.25–31, 09.22 – 10.02, 10.16–20, 10.28

Coverage / Duty Cycle

The fraction of possible time intervals containing partial or complete images during each mission phase is as follows:

	<1996.04.20 (Record count only)	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 (Record count only)
Partial	0	0	.00001	0	.00027	.00077	0
Complete	0	0	.00001	0	.00027	.00077	0
