Scientific paper

Nonlinearity of count rate an important instrumental characteristic of the FOC and affects many of its observations. The Intensity Transfer Function for flat fields was well studied in two SV calibration programs. Nevertheless, it has been over three years and it is quite possible that the ITF curves have changed significantly in that time. Since these ITF curves form the basis for virtually all our methods of determining the amount of nonlinearity (even for point sources) it is important to verify that there have been significant changes. The original SV proposals covered 4 different formats; this proposal will use only two formats: the 512x512 and the 512 zoomed x 1024 formats. Like the SV proposals, the ITF is measured by taking exposures using the onboard LEDs at increasing levels of illumination. All observations are to be carried out in parallel mode.
