The full association consists of a list of exposures and products. This field completely identifies an association. This is the OPUS value used for the keyword ASN_ID. It has the following format: IPPPSSAAa where: I = instrument code (e.g., N for NICMOS, O for STIS), PPP = program_id SS = obset_id of the first associated exposure, AAa = the two-character sequence (AA = 01,02,...) is unique within the obset SS; plus the product id (a) that is always 0 for associations and primary products.
