Three properties of the Image Photon Counting System (IPCS), flat-fielding and the limiting SNR ratio resulting from granularity, the nonlinearity at high count rates, and the statistical properties of photon noise, are discussed based on recent IPCS data. Results suggest that correction of granularity (flat-fielding) is highly desirable, and that obtaining a useful flat-field should usually be feasible. It is found that the IPCS is not linear at any count rate, and though the parameter necessary for a calibration may be experimentally determined, high count rates in narrow features pose intractable problems. It is also shown that the statistics of IPCS data need much care at high count rates, and that at low rates the approximation of adjacent pixels containing independent photon noise is reasonable.
