hmi.rdVfitsf_fd15

Data Series Class: ring fits for flows
Creating Module: rdfitf
Input Data: hmi.rdVpspec_fd15

Data Processing Status

Data for CR 2096:240–2125:030 (1 May 2010 – 16 July 2012) were based on data mapped and tracked using a camera position angle that was subsequently established to about 0°.07 in error and corrected. Reprocessing of the tracked cubes using the corrected angle, and of the data products dependent on them, is complete.

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:

Records for CR 2096–2101 that were reprocessed in 2020 (between Sep 27 and Dec 8) were subsequently removed due to an error in the tracking code used at the time on which the data were based.

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