hmi.rdVfitsc_fd30

Data Series Class: ring fits for structure
Creating Module: rdfitc
Input Data: hmi.rdVpspec_fd30

Data Processing Status

Originally only fits at the 17 tiles on the equator and the central meridian were performed . Beginning with CR 2172 (25 Dec 2015), the fits have been performed for all 69 tiles. Tiles off the equator/meridian cross have been either retrospectively fit or included in reprocessing for all previous rotations.

Data for CR 2096:240 through 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.

Data for CR 2202:270, 2202:210–180, and 2203:270 were based on data tracked without background subtraction.

Data for CR 2098:360 through CR 2234:005 are based on data mapped and tracked using an ephemeris value for the Carrington longitude of disc centre that was in error by 0°.0819. Data reprocessed since 2020.09.26 are based on tracked data corrected for this error.

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

v 1.2 : CT 2126:360 – 2171:030 (on equator or central meridian), 2172:360 – 2186:030
v 1.3 : CT 2096:240 – 2125:030, 2126:360 – 2171:030 (off equator or central meridian), 2187:360 –

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

[2096–2125] : 6288 records, originally processed 2010.11.18 – 2012.08.27, reprocessed 2021.01.12 – 11.06
[2126][360] : 17 records, originally processed 2012.08.17, reprocessed 2012.10.20
[2127][330][][0][-60,-30,-15], [2127][330][330][-60] : 4 records, originally processed 2012.10.30, reprocessed 2012.10.31
[2196][030] : 69 records, originally processed 2017.11.16, reprocessed 2017.12.14
[2197][360–300] : 207 records, originally processed 2017.11.18–23, reprocessed 2017.12.17–21
[2204][270–240] : 138 records, originally processed 2018.06.13–15, reprocessed 2018.07.08–10

Data Notes

The fixed arguments to rdfitc that have been used in populating this series are:

out= hmi.rdVfitsc_fd30 (required)
guessfile= `show_info -pq ds= "yale_cb.guess_table[1]"`/freq.guess
fmax= 5500

Although setting of the keywords n_i_fits etc. for the mode fit counts and frequency extrema by order was implemented in version v 1.1 of the processing module, the relevant keywords were not added to the data series until processing with version v 1.2 began. Consequently the values of these keywords are unset (Postgres NULL) in all records processed with versions below v 1.2.
