We present results from the spectral analysis of the Seyfert 1.9 galaxyMCG-5-23-16, based on ASCA, BeppoSAX, Chandra and XMM-Newton observations. Thespectrum of this object shows a complex iron Kalpha emission line, which isbest modeled by a superposition of a narrow and a broad (possibly relativistic)iron line, together with a Compton reflection component. Comparing results fromall (six) available observations, we do not find any significant variation inthe flux of both line components. The moderate flux continuum variability(about 25% difference between the brightest and faintest states), however, doesnot permit us to infer much about the location of the line-emitting material.The amount of Compton reflection is lower than expected from the total ironline EW, implying either an iron overabundance or that one of the two linecomponents (most likely the narrow one) originates in Compton-thin matter.Comment: Accepted for publication in A&
