References to multiple coordinate systems appear in the headers of STIS data, tied to the spacecraft frame, the user frame, and the aperture frame. ... The coordinate system in IRAF is aligned with the user frame. ... The angles associated with these frames that appear in the headers of STIS data files are: . ... 1.00 . ...

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). ...

... Miriad has a couple of tasks available for finding positions of sources (see also cgcurs in Chapter 17 ). ... It fits a 2-D parabola to the image intensities in a 3 by 3 pixel box centred on the brightest pixel in a specified region and reports the fitted location and intensity. ... Input image . ... The quality of your fit can improve significantly by selecting a snug region, and/or using the clip keyword to keep pixel values with little signal (e.g. sidelobes and noise) out of the fitting process....

... The internal coordinate system used by arfgen is DET, so if the input coordinate system is EQPOS, POS or TEL, a conversion to DET is performed. ... The conversion from EQPOS to DET in general requires knowledge of the spacecraft attitude. ... It is recommended to use DET coordinates if the mean attitude over the exposure period varies significantly from the start attitude. An intermediate stage of the conversion from equatorial to detector coordinates is via the telescope position (theta, phi). ...
