Description

Line-of-sight magnetic field from 30-second observations in high-resolution mode, sampled at second 30 . The data are acquired occasionally during certain targeted campaigns, with different subrasters of the full CCD image populated.

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	.038	.150	.213	.092	.005	0
Complete	0	.038	.148	.210	.091	.005	0

Superseded records: 0 in addition to 754679 valid
