Overview

SSSHME contains a listing of the full Einstein Solid State Spectrometer (SSS) database as it was originally archived on the HME tapes and is presently directly accessible using the GSFC IBM mainframe.

Description

For a description of the Einstein Solid State Spectrometer, please type `dbhelp/dbname=SSS`. The SSS database contains a higher-level version of the majority of the SSS data which was extracted, for example, with a coarser time resolution than the original data.

The original data can be accessed using the GSFC IBM 3081 mainframe computer and analyzed using the HEAO-B (Einstein) SSS software package. The data were originally archived on the so-called HME tapes and the present SSSHME catalog is a listing of the SSS data in this archive. The SSSHME listing can be used, for example, to find out precisely when a target was observed; also, by comparison with the SSS database, one can discover which observations were included in the SSS file of a particular source on a particular day. No data product is associated with this catalog. People who are interested in accessing the complete SSS database should get in touch with the SSSHME contact person.

There are typographical errors in this listing, as some of the information was apparently hand-entered. For example, some of the positions are incorrect, as can be found by a comparison with the Einstein aspect solutions for the same time period. Also, the source naming convention is not consistent and different observations of the same source may well be referred to by different names. Thus, searches by name should always be accompanied by searches on coordinates. The SSSHME listing contains observations up to day 660 (1979, day 295 = Oct 22). However, the SSS cryostat ran dry sometime between day 641 and day 651, so that all observations made on and after day 651 (1979, day 286 = Oct 13) are, in fact, useless.
