Available Processing Levels

For a general description of processing levels within the SHA database, see the SOI Datasets description.

lev1

Daily sets of calibrated images (Dopplergrams, magnetograms, intensity, and modulation), organized by observing site and by observable. These data correspond to the GONG data sets processed with Hankel Geometry, SCPzi, where SC = {bb|ml|le|ud|td|ct|tc} and P = {v|i|m|b}. The data have been ingested "as is", with all images from a given observing day (corresponding to the calendar day at the site) collected into each data set. (Only the the populated series are listed.)
Site Observable
Learmonth Doppler Zeeman Intensity Modulation
Udaipur Doppler Zeeman Intensity
El Teide Doppler Zeeman Intensity Modulation
Cerro Tololo Doppler Zeeman Intensity
Big Bear Doppler Zeeman Intensity

lev1mrg

Selected daily sets of merged Dopplergrams as provided privately by the GONG project.

lev2track/trackps

1664-minute tracked cubes of the merged Doppler data arranged in "dense-pack" strips, and the corresponding power spectra.
