This server now also offers Contour plots - before using it please read important notes under general instructions and image type.
This postage stamp server for the VLA FIRST Survey returns radio images of the sky in FITS or JPEG format, or as a CONTOUR plot. For more about a form entry, click on its label.
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 0.15 mJy/beam.
the FITSview family of FITS image viewers is available for a variety of computer systems. For a short discussion of installing external viewers for FITS files click here.
In publications using FIRST results please reference Becker, White & Helfand (1995).(Astrophysical Journal 450, 559-577).
