The Digitized Sky Surveys were produced at the Space Telescope Science
Institute under U.S. Government grant NAG W-2166. The images of these
surveys are based on photographic data obtained using the Oschin
Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope.
The plates were processed into the present compressed digital form
with the permission of these institutions.
The Oschin Schmidt Telescope is operated by the California Institute
of Technology and Palomar Observatory.
The UK Schmidt Telescope was operated by the Royal Observatory
Edinburgh, with funding from the UK Science and Engineering Research
Council (later the UK Particle Physics and Astronomy Research Council),
until 1988 June, and thereafter by the Anglo-Australian
Observatory. The blue plates of the southern Sky Atlas and its
Equatorial Extension (together known as the SERC-J), as well as the
Equatorial Red (ER), and the Second Epoch [red] Survey (SES) were all
taken with the UK Schmidt.
