VLSS Postage Stamp Server
This postage Stamp server for the VLA Low-Frequency Sky Survey (VLSS, formerly 4MASS ) returns radio images of the sky in FITS or JPEG format, or as a contour plot. For detailed general instructions or information about this survey, see the Help File under "general"; or use the links on the forms for help about each item.
This is the interface for the original VLSS. For updated images please look here.
The VLSS survey is being carried out by the NRAO and the Naval Research Lab.
Note: The VLSS survey is not yet complete.
Note: The southern completeness limit is -30 degrees but there is decreasing sky coverage to -36 degrees.
Note: these images will have a relatively high dynamic range which will cause them to appear as white dots on a black background unless the viewer used has suitable control over brightness, contrast and the range of values to be displayed. The "noise" level in these images is about 100 mJy/beam.
Entire 14 x 14 deg fields can be obtained here or through a simplified form interface. The entire source catalog as a FITS binary table and software here. (Reminder: shift-click will generally force your browser to save the requested image to a file rather than displaying it in a text window.) A catalog browser server is also available to lookup positions in the catalog.
