hmi.rdVavgpspec_fd15

Data Series Class: average ring spectra
Creating Module: datavg
Input Data: hmi.rdVpspec_fd15

Data Processing Status

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

v 1.2 : CR 2126–2146
v 1.3 : CR 2147–2154
v 1.4 : CR 2155–2159
v 1.5 : CR 2160–2201
v 1.7 : CR 2202–2213
v 1.8 : CR 2214–2224
v 1.9 : CR 2096–2125, 2225 –

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

[2096–2125] : all 8487 records, originally processed 2011.06.28 – 2012.09.10 reprocessed 2021.01.17 – 11.06
[2182][+22.5][-60.0,-52.5,-22.5,+45.0] : 4 records, originally processed 2017.01.11, reprocessed 2017.01.11
[2182][+15.0][-45.0,+15.0,+75.0] : 3 records, originally processed 2017.01.11, reprocessed 2017.01.11
[2182][+07.5][-45.0,-30.0,+00.0,+37.5,+67.5] : 5 records, originally processed 2017.01.11, reprocessed 2017.01.11
[2182][+00.0][-67.5,-30.0,+00.0,+37.5,+67.5] : 1 record, originally processed 2017.01.10, reprocessed 2017.01.11
[2196] : 284 records, originally processed 2017.11.17, reprocessed 2017.12.15

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.

Data Notes

The fixed arguments to datavg used in populating this series are:

out= hmi.rdVavgpspec_fd15
mean= logP
pkey= CMLon
mscale= 0.0005
mzero= -11.5
copy= "CarrRot,LatHG,LonCM,DELTA_K,DELTA_NU,D_OMEGA,Apode_f,APOD_MIN,APOD_MAX"

Prior to 1 May 2019, the values of CRPIX1 and CRPIX2 (the WCS pixel location corresponding to 0 spatial frequency in k_x and k_y respectively) in all records were erroneously reported as 192.5. They were all corrected to 193.0 on that date.
