07/03/03 48821 CTB Converted to XML format This relation is used to identify NICMOS associations containing Post-SAA dark exposures. The records are created for all such associations whether or not there are any exposures that use it. There is a separate record for each NICMOS configuration and saa_exit time. The relation is used to allow the linkage of NICMOS exposures to SAA darks that may occur in a previous (replan) SMS. Records having saa_exit_hour values that are a few weeks old have no operational value and may be deleted at any time. There is no reason to archive any of these records. " C11 YYYY.DDD:HH -- This is the hour at which the saa exit occurs. If the exit time is near an hour boundary, a second record with the adjacent hour is also present. This field is used to match with the first 11 characters of nic_saa_exit.saa_exit to create the nic_saa_link records. C15 This is the value from qelogsheet.config that must be the same for both exposures of the association. The same value must match any qelogsheet.config for linked exposures in nic_saa_link. There should be three records with different config values for each value of saa_exit_hour. C3 The program_id of the dark association. See asn_product_link.program_id. C2 Association observation set identifier of the dark association. See asn_product_link.asn_obset_id. " C3 Member number of the dark association primary product. See asn_product_link.member_num.
