This Google drive directory stores the tables resulting from my fitting to the GONG, MDI and HMI observations at low and medium degrees (0 ≤ ℓ ≤ 200|300) for all the data available to date (Korzennik, 2005, 2008a, 2008b, 2023; [ADS: 2005ApJ...626..585K, 2008AN.…329..453K, 2008JPhCS.118a2082K, 2023FrASS…931313K]).
The primary tables list the individual mode frequencies, line-widths, asymmetries and amplitudes. Derived tables list multiplets mode frequencies, line-widths, asymmetries and amplitudes as well as Clebsch-Gordan coefficients, after performing a fit to 6, 9, 18 or 36 coefficients.
All the tables are plain ASCII files, the file formats are described in the following documents:
These ASCII files are also consolidated in tar-compressed sets (up to
20 files in each .tgz
set) for convenience (fewer &
faster downloads).
Almost all the tables have been converted to the Stanford format and
ingested into the password protected JSOC (aka JSOC2) using Schou's
m10qr
file format. These are su_sylvain
data
series, and are available here as well.
Time-series of various lengths have been fitted, namely 36, 72, 144, etc., up to 128x 72 day-long ones, as well as 5x 72 and 10x 72 day-long ones.
The 36, 72 and 360 day-long series are offset in time by a multiple of their respective lengths (no overlap), while all the other ones (144, 288, etc., up to 128x 72 day-long and the 720 day-long) are offset by a multiple of half their respective lengths (50% overlap).
All the time-series start at a time aligned with respect to MDI mission day #1216 (1996.05.01), hence the same epochs are always fitted for each instrument. Although for a few of the long time-series, there is an additional offset and alignment is different (aka 32x, that starts at #6400, not at #6976, i.e., an 8x 72d offset instead of the 16x 72d one).

:
skBo=a2
].skBo=a2+psf
].In the case of my leakage matrices, the upgrade of the GONG detector from a medium-resolution CCD, with rectangular pixels, to a high-resolution one with square pixels is taken into account. Since not all instruments were upgraded simultaneously, some epochs were fitted with a weighted average of the leakage matrix corresponding to pre and post detector upgrade.
I have used three leakage matrices:
B
o
=0
[jsBo=0
].B
o
=0
[skBo=0
].B
o
for that epoch
[skBo=a
].The skBo=a
leakage matrix was used only for the 02e
& 04e time-series, since for longer ones, the mean
B
o
is almost 0.

[skBo=a2

of the spherical
harmonic decomposition performed by Stanford (i.e., includes the
Carrington elements correction).
The skBo=a
cases are not equivalent to the
skBo=a2
cases:
skBo=a
means using a leakage matrix computed for the
mean value of B
o
over the
time-series for each epoch - computed for 144-day and 244-day long MDI
