Description

Computed continuum from either 30-second or 60-second observations in full-disc mode, with constituent photograms at second 00 summed over a 25-min interval under a gaussian-like weighting function, binned by 8*8 pixels, and sampled once ever 12 minutes. The phasing of the sampling minute varies through the mission. The data are part of the MDI Structure Program, and are intended to be continuous throughout the mission.

There is one record every 12 minutes during times of instrument operation. Records for which there is no image (fill records) have the high-order bit of the QUALITY keyvalue set, and have DATAVALS = 0. Approximately 2% 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	.750	.987	.916	.975	.869	0
Complete	0	.605	.967	.902	.953	.860	0

Superseded records: 0 in addition to 637201 valid
