Scientific paper

By observing clusters of galaxies in the X-ray band it is possible to measure the total gravitational mass (dark matter included) perhaps more precisely than the same measure obtained from optical data. How to make this measure with SAX (X-ray Astronomy Satellite) is the aim of this work. The response of the SAX X-ray telescopes to extended spherically symmetric sources is studied in order to set an image-deconvolution procedure. Realistic Monte Carlo simulations of observations of isothermal and polytropic X-ray clusters of galaxies are examined.
