****************************************************** PR # 43022 We propose to observe with ASCA two higly obscured, narrow line Seyfert 2 Galaxies, namely NGC 7172 and NGC 4507, for which the column density of the molecular torus is such to permit to see directly the nucleus above a few keV. We have already successfully proposed XTE observations of these two sources. Simultaneous ASCA observations will provide an unprecedented energy coverage from 0.5 to 200 keV which will permit to test unification models. It is worth stressing that this proposal is not ******************************************************
