mdi.fd_Ic_30s
Description
Intensity of the computed continuum from 30-second observations in full-disc
mode, sampled at seconds 00 and 30. Although 30-second observations are
regularly acquired at second 00 during campaigns, this series is only
populated during minutes in which continuum intensity data were acquired
during both halves of the minute. The data are acquired in either linear or
circular polarization, typically alternating.
There is one record per 30 sec 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 17% 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 | 0 | .005 | 0 | 0 | 0 | 0 |
| Complete |
0 | 0 | .004 | 0 | 0 | 0 | 0 |
Most of the data were obtained during the following campaign intervals:
- 1997.04.07 17:27:00 – 17:45:30

- 1997.04.10 07:13:00 – 07:57:30
- 1997.08.14 01:13:00 – 03:30:30
- 1997.08.14 11:02:00 – 11:40:30
- 1997.08.14 17:56:00 – 1997.08.15 03:30:30
- 1997.08.15 10:58:00 – 11:40:30
- 1997.08.15 17:45:00 – 1997.08.16 04:55:30
- 1997.08.22 14:01:00 – 1997.08.23 03:30:30
- 1997.09.13 01:01:00 – 09:59:30
- 1997.09.13 13:00:00 – 1997.09.14 01:25:30

- 1997.09.15 03:24:00 – 04:59:30
Additional data were taken as part of very brief test/validation
sequences only at the following times:
- 1997.04.02 13:55:00–13:59:30
- 1997.04.02 16:20:00–16:24:30
- 1997.04.03 07:22:00–07:26:30
- 1997.11.04 19:09:00–19:16:30
Superseded records: 0 in addition to 13337 valid.

Special Notes
The following records have not yet been incorporated in this series, due to
incomplete processing in the original pipeline:
- 1997.09.11_14:34:00 – 15:37:30 (98 potential observations)
- 1997.09.11_18:04:30 – 1997.09.12_10:10:30 (1988 potential observations)
- 1997.09.12_12:45:00 – 12:59:30 (28 potential observations)
- 1997.09.13_00:01:00 – 00:59:30 (118 potential observations)

Single 30-sec exposure images were incorporated in this series, even though
they were not part of sequences, at the following times:
