VLSS Source catalog browser
This form searches the source catalog produced by the VLA Low-Frequency Sky Survey (VLSS, formerly 4MASS). This radio survey will use the NRAO Very Large Array telescope and will cover the sky north of a declination of -30 degrees at a frequency of 74 MHz, a resolution of 80" and a limiting peak source brightness of about 500(?) mJy/beam. For detailed general instructions click here or for more about a form entry click on its label.
The VLSS survey is being carried out by the NRAO and the Naval Research Lab.
Note: The VLSS survey has not yet been approved for observation with the VLA. What are available at present are the results of test observations which include only a small portion of the sky. Much of the region between +70 and +80 degrees declination is included.
Entire 14 x 14 deg fields can be obtained here or 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 postage stamp server is also available to obtain FITS images, jpeg or contour plots of smaller regions.
