Summary of the GHRS Calibration Program During Cycle 4
Abstract
A summary of the calibration and performance of the GHRS in Cycle 4 is presented. The GHRS is fully characterized except for three areas that will be covered during Cycle 5: the sensitivity and vignetting for grating G140M; wavelength offsets between the Large Science Aperture and Small Science Aperture; and the photocathode granularity when using the G140L grating. All Cycle 4 calibration programs have now been completed, and as necessary, calibration tables and reference images have been updated.
