Available Processing Levels

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

Level 1

Daily sets of images, organized by observing site. 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. Level 0 data are raw, Level 1 data are calibrated (flat-fielded and dark corrected). Only data sets presently in the archive are highlighted.
