REPEATABILITY OF THE FOS G130H GRATING EXTERNAL WAVELENGTH ZEROPOINT ANURADHA KORATKAR and IAN EVANS Space Telescope Science Institute,3700 San Martin Drive, Baltimore, MD 21218 Abstract. Measurements of the position of the geo­coronal Lyff are used to determine the repeata­ bility of the G130H grating and the external wavelength zeropoint for the first time since launch. ... The 1oe repeatability of the wavelength calibration is 0.159 љ A (0.64 pixels or 39 kms \Gamma1 ). ...

... 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. ...
