Scientific paper

We present RXTE observations of the Seyfert 2 nuclei Mrk 3 and Mrk 348, spanning a period of some 200 days for each source. During the observations, the source intensity varied by a factor ~ 2 and ~ 3 for Mrk 3 and Mrk 348, respectively. The data for Mrk 3 are best described by a varying power-law continuum seen through a column density of NH ~ 10(24) cm(-2) , an unabsorbed and non-varying Compton reflection continuum, together with a strong iron Kalpha emission line. This description is consistent with the reflection continuum originating in the far inner wall of a molecular torus, the nearside of which screens our direct view of the central continuum source. A preliminary analysis of the data for Mrk 348 reveals a complex spectrum which softens as the source brightens.
