Scientific paper

Point source sensitivity curves have been derived for the first order modes G140L (Lambdacentral=1425A), G230L (2376A), G230LB (2375A), G430L (4300A), and G750L (7751A), spanning a wavelength range from 1140A to 10320A. The curves are determined by comparing wide slit (52" x 2") observations of the spectrophotometric standard star CD 153 to a pure hydrogen white dwarf model. The calibration is tested by applying the curves to a Space Telescope Imaging Spectrograph (STIS) observation of the spectrophotometric standard star BD+75D325, and comparing these flux calibrated observations to a calibrated FOS spectrum.
