HMI Ring Diagrams: Processing Status

HMI Ring Diagrams
Processing Status

Observables processing status

Sufficient definitive Doppler data exist to allow for the synoptic processing for Carrington times 2096:245 – 2120:335 (1 May 2010 – 8 February 2012). Ring-diagrams synoptic data sets are complete for the period(s):

2096:095 – 2119:165 (12 May 2010 – 24 January 2011)

There are several intervals when the duty cycle was too low for the 5° charts and a few for the 15° charts (see below).

We have discovered a number of cases (all so far in 2116:090 lat -2.5) in which the rdVfitsc_fd05 fit files were not properly written to disk, even though the rdfitc module clearly succeeded in fitting the spectra. A search for other cases (likely due to hardware failures) is underway. The known bad records were all created at the time of a SUMS disk controller failure, between 20:44Z and 21:09Z on 2011.12.14. There were a total of 505 records created in this series between 20:30 and 21:15 on that date, all in the latitude range -20.0 through +00.0 for 2116:090. During this 45-min period there were also 420 records created in rdVfitsf_fd05[2116][085] (lon 072.5 - 095.0). There were no records created in rdVfits*_fd15 and rdVfits*_fd30 nor in the inversion results. (Any bad records in the tracked cubes and power spectra would be trapped by downstream processing failures.)

Notes on Individual Series

N.B.: None of the listed hmi_test series are archived. Records from incomplete mosaics for a given analysis time may be removed to make more disk cache space available. Series hmi_test.rdVfitsf*, hmi_test.rdVfitsc*, and hmi_test.rdVflows* have an archive flag of -1, meaning that their records are automatically removed when the corresponding data files disappear. In the following list, "empty", "partial", and "complete" refer to the number of records in the corresponding intervals with data segments on line. Empty records from series hmi_test.rdVtrack* and hmi_test.rdVpspec* will be removed when no existing records in other series link to them.
