X-ray variability in a sample of Seyfert 1 type AGN.
Abstract
X-ray observations of several Seyfert 1 type AGN observed many times with EXOSAT are presented and analysed. The spectral parameters are extracted independently in the medium and soft X-ray spectral ranges. The variations observed in the two spectral bands and their relation are discussed and compared to the spectral variations observed in other well known sources.
