Processed Data Product
The raw data product is processed into several formats. These are abreviated
and categorized below as:
|DOP|| = Dopplergrams (1 computed per minute)|
|SHC|| = Spherical Harmonic Coefficients (1 per minute)|
|TMS|| = Time Series (of the SHC, computed on daily basis)|
|512 PS|| = Power Series|
|32K PS|| = Power Series computed over a 22-44 day run|
|64K PS|| = Power Series computed over a 45-89 day run|
|128K PS|| = Power Series computed over a 90-177 day run|
Duty-cycle percentages are computed by dividing minutes of collected or
processed data in a 36 day month by
total minutes in a 36 day month (36 x 24 x 60 = 51840).
O = month being processed, but not finished
X = processing finished; duty-cycle percentage pending
A box colored like this:
means the calculated number is in-progress.
Clicking on the YEAR number in the upper left-hand corner of the table
will provide a text listing of the raw data product collected for the
entire year. A series of "****" indicates that no data was collected because
of poor weather or temporary equipment problems.
Clicking on the duty-cycle percentage in the 'DOP' column will provide a
start and stop range of dopplergrams computed and the total number of
dopplergrams in that sequence. The last column in this file indicates if the
data has been archived and if it is available for download from Stanford.
The dopplergrams are converted into FITS format and made available to the
scientific community through the Stanford web site at
Clicking on the duty-cycle percentage in the 'SHC' column will provide a
start and stop range of the spherical harmonics computed and the total
number in that sequence. Also displayed are the average computed heliographic
coordinates and ephemeris values computed for the given day at noon.
At the bottom of the table are links to graphical plots of the observational
history of collected raw images. There are two different plots that show
the MWO-60' history overlayed with blocked off times of start and end times
of GONG months, and a separate plot with overlayed start and end times of
Carrington rotations. These are available as a jpeg image and as a downloadable
