We present an XMM-Newton observation of the nearby dwarf galaxy IC 2574. This galaxy is part of our ensemble observed within a multi-frequency campaign to study the physical conditions of the interstellar medium in dwarf galaxies in general. Here, we focus on the diffuse soft (0.2 - 0.5 keV) X-ray emission associated with IC 2574. Since this emission is expected to be quite faint we have to reach the true X-ray background intensity level. For this aim, we have to account for unrelated diffuse X-ray emission and for the vignetting of the X-ray mirrors aboard the XMM-Newton satellite.
