"Calibration Product Review for the GHRS in Early Cycle 4" 11/94 PostScript (144 Kb)

The tables in this document provide a history (as of 30 September 1994) of the differences among the reference images and tables which are used by the Post Observation Data Processing System (PODPS) to calibrate GHRS data. It is intended to be updated as needed. (See also text Abstract). Below, we list updates to the tables in ISR-067.
