Data Product Descriptions

hmi.rdVavgpspec_fd05

Data Series Class: average ring spectra
Creating Module: datavg
Input Data: hmi.rdVpspec_fd05

Data Processing Status

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

The fixed arguments to datavg used in populating this series are: Prior to 1 May 2019, the values of CRPIX1 and CRPIX2 (the WCS pixel location corresponding to 0 spatial frequency in kx and ky respectively) in all records were erroneously reported as 64.5. They were all corrected to 65.0 on that date.
