07/03/03 48821 CTB Converted to XML format This relation is used to provide the tool, UPDATE_QODATA, with a mechanism to assign a product_id and member_name (of a product) for NICMOS or any that has multiple products. The product_id is correlated with the unique value of EXP_TYPE in qeassociation table. This is a one character product_id that supercedes the last character of the association_id to form the member-name of a product. C4 This is the identifier type for a Science Instrument (SI). The current SI list for qeassociation candidates are: NIC - NICMOS - Near IR Camera - Multi-Object Spectr. STIS - Space Telescope Infrared Spectrograph STIS only has one product_id but many exp_type values and will not appear in this table. C12 This field describes the role of the exposure in the association. Valid values for NICMOS exposures are (EXP-TARG, EXP-BCK1, EXP-BCK2, ..., EXP-BCK8)." C1 This is the last character of an member_id of a product. The first eight characters of the id are the same as the association_id. The first product_id is 0 which forms a member_name that is the same as the association_id. PRODCODE_TYPE Assign product_id by exp_type. OPUS unique clustered
