ST-ECF Instrument Science Report WFC3-2005-17 Ground tests of the WFC3 UVIS grism 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. ... Orders from -8 to +8 are labeled. ... The flux in the -1st order varies between 20% and 60% of that in the +1st order over the wavelength range. ...

... 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...
