Astrophysics with All-Sky X-Ray observations: 3rd International MAXI Workshop (RIKEN, 10-12 June 2008)

MAXI, an all-sky X-ray monitor to be on-board on the ISS (International Space Station), carries two kinds of X-ray cameras: GSC (Gas Slit Camera) and SSC (Solid-state Slit Camera). Both X-ray cameras are scanning imagers combining position-sensitive detectors and collimators with one-dimensional FOV (field of view). They covers 90 % of the whole sky every 90 minutes of the ISS orbital period. The response functions of these cameras for any X-ray sources on the sky depends on the ISS attitude, which always varies according to the orbital motion of the ISS. We are developing software to build response functions for any X-ray source on the sky from the source position coordinates, the instrument calibration data, and the ISS configuration parameters. We introduce the standard scheme of the MAXI data analysis and the response builders used in it. We then present the preliminary results of the response builders and the observation simulator which are currently being developed.
