This WWW form allows the user simplified access to images produced by the NRAO/VLA Sky Survey (NVSS). This service determines which NVSS image is desired based on a celestial position and returns either the image directly or a Web page with a link to the file. ... The NVSS Postage stamp (small FITS file) server can be used to obtain images with other geometries.) ... Web browsers use external viewers to display files like FITS images which they do not understand. ...

... This function accesses the small scale variation CCF flatfield map (PixToPixSens) and returns an image with the requested size, for the requested detector position and at the maximum detector resolution. The CCF PixToPixSens file comprises of a 2048x2048 image array. This file is read. ... The algorithm assumes that the PixToPixSens file is at full detector resolution (2048x2048 pixel). ... The CAL directly extracts the pixel to pixel variation map from the image extension PIXTOPIXSENS. ...

If the image header contains World Coordinate System information, SAOtng will display WCS positions as the mouse is moved across the image. The format for the display is controlled by the Coords Menu (or using the right mouse button on the screen WCS display). ... WCS information is displayed on the lower part of the image. ... The coordinates are returned in the current format, (e.g. if your image supports WCS information, you can get RA/Dec output). ...
