The following test data series (unarchived, and with all SUMS data now aged
off the disc cache) have been removed:
- hmi_test.rdV2track_fd30

There are sufficient definitive data to allow for the synoptic processing
of data for Carrington times 2099:110 – 2104:005.
Ring-diagrams synoptic data sets are nearly complete for the period
2100:030 – 2102:005 (3 Sep – 30 Oct). The 15° cfits are
missing for 2102:015, and there are two periods when the duty cycle
was too low for the 5° charts (see below).
In addition, I have processed the data for the period
2100:360 – 2100:275 (Aug 9–16), corresponding to part of
the time when the targte active regions for the next LoHCo workshop
were on the disc, and plan to extend the coverage backward in time,
following resolution of problems with the data averaging that have
come to light.
Note that much of the October data include gaps due to
the daily eclipses; duty cycles as low as 80% for some of the 9-hour
5° tiles occur frequently. There was one 9-hour period centered on 2102:230
(12 Oct) during which the duty cycle was below 40%, due to spacecraft rolls.
Much of the data from this period could be recovered with special processing,
however any period with a duty cycle below 70% is rejected by the normal
pipeline. Consequently there will be no 5° data for that period. Other
9-hour periods for which the duty cycle is below the acceptable threshold
are 2102:050 (26 Oct) and 2103:290 (4 Nov). The 27-hour duty cycle for
2103:285 (5 Nov) is 68%, slightly below the automatic rejection threshold.
Forcing of the 15° processing for that period may be in order.
Definitive processing status
The following series have been processed with archiving of the data products:

Definitive synoptic data products: SUMS Unit Sizes
All of the definitive ring-diagram series have now been published and are
available for public (non-team) export from JSOC and also for mirroring
by any NetDRMS sites.
As discussed before, the data segments for all of these series are archived
for various reasons, either the quantity of input data (for averages and
tracked data), the computing resources (for ring fits) that would be required
to reproduce them, or the expected demand for repeated access (spectra,
inversions).
Because of the way the data are processed, it is impossible (or at least
useless) to set a unit size of more than 1 for the rdVfitsc*,
rdVflows*, and averaged data series, even though the typical segment
sizes are very small. Likewise, it is impractical to set a unit size of more
than 1 or 2 for the 15° and 30° cubes and tracked spectra because of their
large size. The unit sizes I propose are as follows:
- averages
- tracked cubes
- hmi.rdVtrack_fd05 — 25
- hmi.rdVtrack_fd15 — 1
- hmi.rdVtrack_fd30 — 1
- power spectra
- hmi.rdVpspec_fd05 — 40
- hmi.rdVpspec_fd15 — 1
- hmi.rdVpspec_fd30 — 1
- ring fits
- hmi.rdVfitsc_fd05 — 1
- hmi.rdVfitsc_fd15 — 1
- hmi.rdVfitsc_fd30 — 1
- hmi.rdVfitsf_fd05 — 2748
- hmi.rdVfitsf_fd15 — 284
- hmi.rdVfitsf_fd30 — 69
- derived data
- hmi.rdVflows_fd15_frame — 1
- hmi.rdVflows_fd30_frame — 1
In the multi-unit series the records in a given storage directory
correspond to the regions in one or a few latitude strips at a given time.
Test processing status
The following series were processed from an earlier test version of the
Doppler data. They have been removed and will be replaced with products
of test scripts or modules processing definitive Doppler data.

Notes on Individual Series
N.B.: none of the listed series are archived. Records from incomplete
mosaics for a given analysis time are likely to be removed to make disk
cache space. Current usage is about 18 TB for hmi_test.rdVtrack_fd*
and 12 TB for hmi_test.rdVpspec_fd*. The fits use a negligible
amount of disk space, but may be cleaned to provide consistent and
complete record samples
