The timing properties of Sco X-1 along its Z track with EXOSAT

van der Klis, Michiel; Dieters, Stefan W.

We present a systematic, homogeneous analysis of all the EXOSAT ME, high time resolution data on Sco X-1. We investigate, for the first time, all power spectral properties of the <100Hz quasi-periodic oscillations (QPO) and noise of Sco X-1 as a function of position on the Z-shaped track traced out in the X-ray colour-colour diagram. For this p…

X-ray analysis of the cluster 3C 129

Leahy, D. A.; Yin, D.

The cluster 3C 129 is classified as a rich cluster. An analysis of the properties of the cluster 3C 129 from ROSAT PSPC and HRI, Einstein IPC, and EXOSAT ME observations is presented. The mean temperature from a joint fit of the ROSAT PSPC and EXOSAT ME data is 5.5(+/-0.2)keV. The luminosity is 0.6x10⁴⁴ergs^-1 in 0.2-2.4keV an…
