Data Product Descriptions

hmi.rdVtrack_fd30

Data Series Class: mapped and tracked data cubes
Creating Module: mtrack
Input Data: hmi.V_45s

Data Processing Status

Data for CR 2096:240–2125:030 (1 May 2010 – 16 July 2012) were 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 26 Apr 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.
