NVSS Point flux density Server

Return the flux density at a given position, or list of positions from NVSS images.

In publications using NVSS results please reference Condon, et al. 1998, AJ, 115, 1693; a preprint of this paper which describes the design and techniques of the NVSS is available here. The NVSS survey now complete. Entire 4 x 4 degree fields may be obtained as FITS files using either a Web browser or ftp. (Reminder: shift-click will generally force your browser to save the requested image to a file rather than displaying it in a text window.) For the latest information and detailed descriptions of the NVSS survey see its home page. An online source catalog search is also available.

Users of the AIPS task IMAGR often need to image extra fields covering nearby confusing sources. A RUN file generator produces the required list of field offsets for NVSS sources whose flux densities, attenuated by the primary beam, exceed a chosen cutoff.
