Radio Science Documentation Bundle

This bundle contains documentation about data products that are collected using radio science and supporting equipment. With one exception, each member collection contains one or more versions of a single Software Interface Specification (SIS) or an equivalent document. A SIS describes the format and content of a data file at a granularity suffient for use -- typically byte-level, but sometimes bit-level. Examples of products and descriptions of their use may also be included in a collection, as appropriate. The exception is the DOCUMENT collection, which contains supporting material -- usually journal publications, technical reports, or other documents that describe investigations, analysis methods, and/or data but not at the level of a SIS. Members of the DOCUMENT collection were usually released once, whereas a SIS often evolves over many years.
