APPLAUSE DR3s (applause_dr3s)


The APPLAUSE DR3s contains metadata about the Solar photographic plates of the Einsteinturm and data extracted from the digitzed plates.

The metadata characterizing observation and instrument are collected in table solarplate, the scan process in table scan.

Tables level0, level1 and level2 contain the data resulting from the different processing applied.

  • level 0

    is the result of converting the scan (tiff format, 8bit ) into a photographic positive image

  • level 1

    processing results in a resampled 16bit image, calibrated and with standard solar orientation

  • level 2

    contains the limb-darkening corrected full-disk with enhanced contrast

For a more detailed description of the processing and its results see: Pal, P., et al. , Solar Observatory Einstein Tower — Data Release of the Digitized Solar Full-disk Photographic Plate Archive.
