... After the data from an observation have been received and processed through the STScI pipeline, hardcopy products ( paper products ) are generated which summarize the data obtained. ...

... 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. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

... The association process creates an output table that contains the following columns: . A character column labeled :SCI containing the names of the scientific frames. ... A character column labeled `exptype' (i.e DARK, FF, etc) containing the names of the associated exposures . An integer column QUAL_`exptype' (i.e QUAL_DARK, QUAL_FF, etc) containing for each associated frame its quality flag. ... Figure: Association of DARK exposures with scientific frames . ...

... The processing of these associated images presents new challenges to the HST data processing pipelines, which heretofore operated only on single images. ... Stage 1 (CALNICA) calibrates individual exposures without information from other members of the association. ... Stage 2 of calibration (CALNICB) only operates on associated images that have previously gone through CALNICA processing, and creates combined images for each distinct (non-overlapping) pointing within the association. ...
