SIRTF FLS/VLA Postage Stamp Server
This is a postage Stamp server for VLA observations of the SIRTF First Look Survey. First Look Survey lies inside the SIRTF "constant viewing zone" near the north ecliptic pole. It covers about 5 square degrees in a region having a relatively faint cirrus foreground, centered on J2000 RA = 17 18 00., declination = +59 30 00. The VLA image of this field has a resolution of 5 arcseconds FWHM and an RMS noise of 23 microJy/beam at 1.4 GHz. The region of the sky covered can be seen here. This server returns radio images 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.
For more information about the SIRTF FLS/VLA, see its home page.
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 20 uJy/beam.
An image of the entire field 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 catalog browser server is also available to lookup positions in the catalog.
