Information on resource 'DASCH in the VO'

This is a re-publication of the metadata from StarGlass, an information service operated by Harvard College Observatory (HCO) which primarily indexes the holdings of the HCO Astronomical Photographic Glass Plate Collection. This collection is the world's largest archive of astronomical photographic glass plates, consisting of more than 550,000 images documenting the entire sky over a century-long time baseline. Approximately 430,000 plates in the collection, representing the subset of sky images deemed suitable for astrometric and photometric calibration, have been digitized at high resolution by the DASCH project. StarGlass makes available both photographs and calibrated scientific data when available. This resource re-publishes the metadata in separate tables for “narrow” and “wide” (extremely wide-field) plates. The narrow plates are also published in an obscore table and as a SIAP2 service.
