HyperLeda Help


HyperLeda provides links to DSSdisplay, a JavaScript application we have developed to extract and display Digital Sky Survey Images.
The links are symbolized by "I" or by the coordinate string. The field size are set by default to 5 arcmin and can be changed from the DSSdisplay window. The source location of DSS may also be chosen from the DSSdisplay window.
The Digitized Sky Survey was 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.
