Description

Computed continuum from 30-second observations in high-resolution mode, sampled at second 30. The data are acquired intermittently during various campaigns, with two different subrasters of the full CCD image populated (sizes 700*700 and 1024*800). The data are acquired in linear polarization.

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	.00084	0	<0.00001	0	0
Complete	0	0	.00084	0	<0.00001	0	0

Superseded records: 0 in addition to 972 valid

The data were acquired in sporadic brief campaigns or test/validation sequences between 1997.03.07 and 2009.09.02. Almost all of the data were acquired on 1997.07.07–08.

Special Notes

The DSDS data series sha.dsds[mdi][lev1.5][hr_Ic_1024x600_01h] was erroneously created with a name implying a computed continuum observable. It actually contains data for continuum filtergrams, not computed continuum. All of its records are duplicated within the series sha.dsds[mdi][lev1.5][hr_I0_1024x600_01h] It was consequently not included in this series.
DP 4d483e00 was always acquired in conjunction with DP 40483e00 (mdi.hr_I0).
DP 4d483240 was always acquired in conjunction with DP 4a482240 (mdi.hr_V) and 44483240 (mdi.hr_Ld).
