... Determine the net instrument response desired. ... Use a numerical algorithm, the convolution network (discussed in detail below), to search for the solution that provides the desired mapping of the observed data to the desired form. ... We first made preliminary studies investigating recovery of images that have been broadened by the HST's mirror by modeling its PSF as shown in Fig. ... Our recovery procedure was applied also to spectral data, in this case to a tunable diode laser (TDL) spectrum. ...
ST-ECF Instrument Science Report WFC3-2005-07 Ground tests of the WFC3 NIR grisms S. S. Larsen, H. Bushouse, J. R. Walsh March 2005 ABSTRACT The fundamental parameters of a slitless dispersing element are the geometrical configuration of the spectral orders, the dispersion relation relating pixel offset to wavelength and the sensitivity of each order. Based on thermal vacuum tests, the performance of the WFC3 near-IR G102 and G141 grisms has been assessed. ... WFC3 IR Grism Modeling and Rotations. ...

... Complex astrophysical phenomena could now be studied spectroscopically: the X-ray absorption line forest intrinsic to Seyfert galaxies; the interaction between AGN jets and intracluster media; hot winds of starburst galaxies; stellar coronal plasmas; the charge -exchange emission of Mars' exosphere; the X-ray irradiation of protoplanetary disks; and the myst erious flat-topped spectral line shapes of O star winds. ... We estimate that Gen-X will be able to detect and resolve 20, 000 stars in NGC...
