Instrument Handbooks
The GHRS Instrument Handbook is the single most useful reference about the GHRS except for this data handbook; it describes instrument operating modes as well as observing strategies. The instrument handbook is critical for understanding why a series of observations may have been obtained in a particular manner at a particular time. The flight software and operating procedures for the GHRS changed continually over its life as errors were corrected and new features installed. The different versions of the instrument handbook document the history of these efforts (as do the ISRs, described below).

Instrument Science Reports
Instrument Science Reports (ISRs) are technical papers issued by STScI that summarize, for example, calibrations, or new operating features. Ninety-one GHRS ISRs were written. Sometimes ISRs provide details not available elsewhere, but in general we have tried to encapsulate the contents of ISRs into this data handbook so that archival researchers will not need to refer to them. There are some cases where the ISR treats a specialized subject that is beyond the scope of this handbook, and we note those where appropriate.34.4.2 GHRS Web Resources
STScI maintains extensive resources on the World Wide Web. GHRS resources can be found by using the search mechanism. You should always check there for changes or updates. STScI's home page is at:
