hmi.rdVfitsc_fd15

Data Series Class: ring fits for structure
Creating Module: rdfitc
Input Data: hmi.rdVpspec_fd15

Data Processing Status

Originally only fits at tiles on the equator and the central meridian were performed (37 or 38 tiles, depending on B0). Beginning with CR 2172 (25 Dec 2015), the fits have been performed for all tiles (281 or 284). Tiles off the equator/meridian cross have been retrospectively fit for CR 2097:300–2098:315 and for CR 2162–2171 as of 29 Aug 2018.

Versions of creating module used to produce records in the data series:

The following records have been subsequently reprocessed and exist in multiple versions in the DRMS database:

For current processing status, see the Ring-Diagram Status page.

See also the status report for the source spectra.

Data Notes

During the period CR 2165–2201, when fits were performed for all tiles, the distribution of number of fits by mode order among the total of 251,612 was as follows: Note that these counts include include reprocessed data for the eight time intervals 2196:030-2197:285, representing an extra 2260 cases.
