... A technique allowing automatic representation by a relatively small number of independent parameters based on the principal component analysis of data sequences is presented. ... In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classification of newly-observed data becomes most urgent, especially if there is a lack of preliminary observational material and theoretical expectations. ...

The Gemini South Adaptive Optics Imager (GSAOI) is a near-infrared adaptive optics camera that will be used with the Multi-Conjugate Adaptive Optics (MCAO) system on the Gemini South 8-m telescope . ... Gemini's major instrumentation goal is to develop its Multi-Conjugate Adaptive Optics (MCAO) system for scientific use on Gemini South. ... Existing adaptive optics systems use a single natural guide star or artifical laser guide star to measure this image blur. ...

... For a certain group of XMM PPS products (e.g. EPIC background maps, EPIC maximum-likelihood source lists, EPIC images, EPIC sensitivity maps) a list of commands is executed stored in an ascii file (hereafter check file). ... The tests include existence and parameter range checks for header key words and source tables columns of EPIC PPS Fits files. ... This check file performs existence and parameter range checks for EPIC PN, MOS1, MOS2 background maps in the energy bands 0,1,2,3,4 and 5. ...
