The Sky Surveys, DSS, and STScI:
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 at Siding Spring.
The plates were processed into the present compressed digital form with the
permission of these institutions.
The National Geographic Society - Palomar Observatory Sky Atlas (POSS-I)
was made by the California Institute of Technology with grants from the
National Geographic Society.
The Second Palomar Observatory Sky Survey (POSS-II) was made by the
California Institute of Technology with funds from the National Science
Foundation, the National Geographic Society, the Sloan Foundation, the
Samuel Oschin Foundation, and the Eastman Kodak Corporation.
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.
