... This thread contains a step-by-step recipe to extract MOS spectra of a point-like source observed in Imaging mode and to create associated response matrices, starting from a calibrated, concatenated event list (either produced with emproc or available as PPS product; here it has the assumed file name MOS.fits ). ... The users should note that the SAS metatask xmmselect allows them to interactively define source and background regions (via ds9) and to run backscale on the fly. ...

Testing the Automatic Detection of Directly Imaged Exoplanets Using Wavelet Analysis Chris Merchantz Introduction · Challenges associated with direct images of planets Distinguish planets in the following way: (1) a minimum flux threshold is from speckles maxima, anddefined for the features that are identified as local (2) the "Exoplanet Recognition Using a Wavelet Analysis Technique" Fig. ... This spectrum is used as template spectrum to recognize planets in a deep image. ...

... Among the objectives of Principal Components Analysis are the following. dimensionality reduction; љ . the determining of linear combinations of variables; љ . ... identification of groups of objects or of outliers. ... Finding a set of principal axes allows the objects to be adequately characterised on a smaller number of (artificial) variables. ... Reduction of dimensionality is practicable if the first new axes account for approximately 75 % or more of the variance. ...
