Determination of geometric distortion in STIS imagesThis is a report on the characterization of the geometric distortion of the Space Telescope Imaging Spectrograph (STIS) Charge Coupled Devices (CCD) and the STIS Far-Ultraviolet Multi-Anode Microchannel Arrays (FUV-MAMA) detectors when used in imaging mode. We find that the amount of the distortion is fairly small over most of the field. The maximum displacement is 1.66 pixels for the CCD and 2.71 pixels for the FUV-MAMA. This data also allows us to determine the plate scale for both cameras. For the CCD the scale is 0".05071 +/- 0".00007 /pixel. For the FUV-MAMA the scale is 0".02447 +/- 0".00001 /pixel in x and 0".02467 +/-0".00002 /pixel in y.
