Scientific paper

The GHRS Point Spread Function (PSF) was measured directly by stepping (dwell scan) the Small Science Aperture across the star HD106343 (program ID: 6210) using the G160M and G270M gratings. Two scan directions were sampled, along the instrument x-axis at wavelengths 1400A and 2700A, and along the +y-axis at 2700A. The scan steps were spaced 0.4 arcsecond apart and went out to a radius of 3.0 arcsec from the star. RAPID mode (sample time of 1 second) was used to measure the counts at each dwell position. Nine points (9) were extracted from the data to define the PSF envelope. The PSF exhibits a low intensity side lobe peaking at a radial distance of ~2.0 arcseconds.
