Examination of the background by High Energy X ray Experiment (HEXE) on the space station MIR

The last results of the HEXE mission showed considerable declinations between the known x ray source positions and the view direction of the HEXE, which reduces the photon flux from the source, significantly in some cases. For this experiment many programs were written and tested for the reduction of data. Quick-look programs are presented that allow the data acquisition. A program was developed that can give the measurement results of the housekeeping counter by way of the catalog system and gathering in plot files. An orbit program is proposed to carry out the center correction for the arrival time of the photons and to study the influences of the geomagnetic field on the background observed by HEXE.
