Description

Intensity of the filtergram at the 0-tuning position, nominally furthest from line center, from 30-second observations in high-resolution mode, sampled once per minute at second 30. The data are acquired intermittently during various campaigns, with different subrasters of the full CCD image populated. Some of the data are acquired in linear polarization and some in combinations of circular polarizations; they are distinguished by the value of the key POLSTATE.

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	.034	.128	.208	.053	.002	0
Complete	0	.033	.123	.206	.053	.002	0

Special Notes

There are far fewer fill records than expected if the series is gap-filled by hour (43 total); they are all in the range:
