SOI Data Sets - prog:mdi_eof - by observable
The data in these series are derived from individual calibrated quick-look data
products of SOI. These data are available for scientific analysis under the
terms of the
SOI Data Policy.
SOI data are made available for automated retrieval and export via both
on-line and off-line mechanisms; see the
Export Help Page.
The data sets included here correspond to observations made with various
combinations of onboard observing and processing procedures in order to
produce sets of consistent measurements of the physical quantities with the
maximum continuity possible. Thus, for example, 30-second exposures from
some minutes have been combined with 60-second exposures from other minutes
in the same hour or day, and missing samples of data normally averaged on
board have been filled in when possible with data averaged from full images
taken at the same time.
Available Processing Levels
For a general description of processing levels within the SOI database,
and information about the search procedure, see the
SOI Datasets description.
- Level 0: raw data converted to image or table files; see
Low-Rate and
High-Rate data pages for data
availability and export requests.
- Level 1: Level 0 data converted to physical units.
Low-Rate and
High-Rate data pages for data
availability and export requests.
- Level 1.4:
level 1 data assembled by physical observable with relevant ancillary data.
This level only exists for data which are not originally 2-dimensional.
- Level 1.5:
same as Level 1.4, but reformatted to two-dimensional grids (as appropriate);
for cropped circular images these data sets are of course about 25% larger
than the corresponding Level 1.4 data sets, but otherwise identical.
- Level 1.4/1.5 by
Time Range:
Finds all data products within a given time range.
Available Data Series
Level 1.5 Data
This is the primary collection of calibrated data products from SOI/MDI
suitable for analysis without special software tools. Most data sets
contain collections of 2-dimensional FITS files (a few may contain
3-dimensional FITS files representing time series of images) with
ancillary data in ASCII form. N. B. The ending dates for the
data and the number of data sets (hours or days) in the lists below
are not kept up to date! Additional data may be available.
Hourly Data Sets (from High Rate Science)
none
Daily Data Sets (from Low Rate Science & Synoptic)
Discontinued Data Sets (for historical interest)
Level 1.4 Data
These data sets are similar to the Level 1.5 data above, except that those
data products originally formatted as one-dimensional lists for purposes
of telemetry conservation retain their original format. The data involved
are primarily either circular crops of the full field from the high-rate
telemetry or any of the various products from the low-rate telemetry. As
with the Level 1.5 data, all digital data are in FITS files, with ancillary
data in ASCII tables. Interpreting the data requires special software
available at Stanford and Lockheed-Martin.
Hourly Data Sets (from High Rate Science)
