High spatial resolution spectral imaging, as done by HST/STIS, has come of age in the last few years with observations of stellar winds and outflows, extragalactic and galactic jets, and rotation curves of galaxies. The potential of this technique is only now becoming realized, since some of the most exciting applications, such as imaging of outflows on sub-arcsecond scales, and studies of the composition of circumstellar disks, require a detailed understanding of the spatial component of the PSF in STIS's spectral imaging modes. Progress has been made toward this goal with observations {calibration proposal 8844} to characterize the wavelength- dependent PSF for 4 stars: BD+75D325, a white dwarf; HD141653, an A0V star; HD115617, a G0V star; and HD181204, an M III-I star. We request funding to complete a study of the wavelength-dependent STIS CCD PSF. This information is essential to fully characterize the instrumental scattered light that adds to the scattered light from the HST primary and secondary mirror. We plan to provide example spectral data as reference for users who intend to measure properties of faint objects in the vicinity of bright stars. Models of the scatter effects will be built to provide better understanding on what can be accomplished with STIS. Also, the data will feed into models for imaging faint sources in the close vicinity of bright point sources.
