"An Analysis of Pipeline Wavelength Calibrations for the First-Order
Gratings of the GHRS in Cycles 4 Through 6"

Howard H. Lanning, David R. Soderblom, Anne Gonnella, and Lisa

May 22, 1997


This Report is based on the execution of the Side 2 calibration
proposals 5600, 6172 and 6898, and Side 1 calibration proposals 5542,
6171, and 6897 (Cycles 4, 5, and 6, respectively). Results indicate
that the default wavelength scale provided by the pipeline data
reduction system has not changed significantly with time during the
past three cycles.
