For flexibility, this table allows an arbitrary number of keywords to be accessed by the programmattic IDs of the astrometry dataset. " C3 BASE_36 When a proposal is accepted into the PMDB by SPSS it must be assigned a unique 3 character base 36 program identifier. This is done by the pmdb -accept_prop command or pmdb -load. It is used for identification of proposals by spacecraft and OPUS software. It is also used in the OPUS and DADS rootname for all archived science data files. Because of flight design software, program_id must be three characters. C2 BASE_36 "An observation set is a collection of one or more alignments that are grouped together based on FGS pointing requirements. That is, if multiple alignments can all be executed using the same guide star pair, they are grouped into the same observation set. " C2 BASE_36 "Observations are numbered sequentially throughout an observation set and are assigned by SMS/Gen. An ob_number is _NOT_ the same as an obset_ID. " C8 "The name of the keyword for has the keyword_value." C68 "The value of the keyword_name. The longest string allowed by FITS is 68 characters. Most keywords have values that are less than 20 characters. " AST_JITTER_KW_TYPE AST keywords supplied by JITTER calculations. OPUS unique clustered
