Description

Line-of-sight magnetic field from 30-second observations in high-resolution mode, sampled at second 30 and binned 2*2 on the camera. The data are acquired occasionally during certain targeted campaigns.

There is one record per minute during hours when there are any images, to assure continuity of certain ancillary data. Records for which there is no image (fill records) have the high-order bit of the QUALITY keyvalue set, and have DATAVALS = 0. Approximately 76% of the records are fill.

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	.0332	.0086	.0001	<0.0001	0	0
Complete	0	.0328	.0085	.0001	<0.0001	0	0

Superseded records: 0 in addition to 49020 valid
