hmi.rdVpspec_fd05

Data Series Class: ring spectra
Creating Module: pspec3
Input Data: hmi.rdVtrack_fd05

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 pending as of 17 Jul 2018.

Data for CR 2202:285–280 were based on data tracked without background subtraction.

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

N.B. For CR 2130:315 records for Latitudes -80.0 – -27.5 were processed with version 1.1, the remainder with version 1.0.

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.
