In­orbit calibration activities of the XMM­Newton EPIC Cameras D.H. Lumb a , Ph. ... Astrophysik, University Tubingen, D72076 Tubingen, Germany g IFCTR del CNR, via Bassini 15, 20133 Milano, Italy ABSTRACT The combined effective area of the three EPIC cameras of the XMM­Newton Observatory, offers the greatest col­ lecting power ever deployed in an X­ray imaging system. ... Determining the effective area and spectral response distributions are thus the most important goals for XMM­Newton calibration. ...

This report discusses the current method by which the APO 3.5-m telescope can be collimated. ... At this time you are NOT trying to set the tilt of the secondary, you are only trying to set its translation to be coincident with the axis of the Cassegrain hole lifting fixture. ... If the camera is exactly on the rotator axis, then the error circle will be centered on the ART crosshairs. If the camera is off the rotator axis, then the error circle will be displaced from the ART crosshairs. ...

X­RAYS AND HIGH REDSHIFT QUASARS Martin Elvis Harvard­Smithsonian Center for Astrophysics, Cambridge, MA 02138, USA (internet: elvis cfa.harvard.edu) ABSTRACT X­ray observations of high redshift (zё3) quasars have yielded a wealth of sur­ prises, both in their emission spectra, and in their absorption properties. ... Only radio­loud quasars, which are relatively X­ray bright, gave enough counts to allow well­constrained spectral fits. ... Larger ff OX equals more X­ray quiet. ...
