LANGUAGE C, FORTRAN, SQL INCLUDE ZSPSS_USER_TYPES.SDDL RECORD WGTUNE_TYPE DESCRIPTION "This relation defines the default values for the tuneable parameters related to the scheduling of SUs. These parameters provide some user control on the priorities and characteristics on the scheduling of SUs, obsets, and alignments. SPSS developers should note that the C&C list data structure (file ZCCL.SDDL) contains a field in the 'CTRL' subrecord which corresponds to to each field in this relation. The CCLIST/CREATE command queries this relation to load those fields with the default values. The CCLIST/MODPARMS program can be used to change the values for a particular C&C list." FIELD max_sci_rtrn TYPE R4 DESCRIPTION "This the weight of the first goal parameter used by the CALENDAR/AUTO program to schedule SUs. The goal is to maximize science return based on priority." END_FIELD FIELD slew_time TYPE R4 DESCRIPTION "This the weight of the second goal parameter used by the CALENDAR/AUTO program to schedule SUs. The goal is minimize major slew time." END_FIELD FIELD si_cha_time TYPE R4 DESCRIPTION "This is the weight of the third goal parameter used by the CALENDAR/AUTO program to schedule SUs. The goal is to minimize science instrument reconfigure time." END_FIELD FIELD time_crit TYPE R4 DESCRIPTION "This is the weight of the fourth goal parameter used by the CALENDAR/AUTO program to schedule SUs. The goal is to control the priority of time critical SUs." END_FIELD FIELD nonsci_time TYPE R4 DESCRIPTION "This is the weight of the fifth goal parameter used by the CALENDAR/AUTO program to schedule SUs. The goal is to minimize non-science time activities which are not included with the second and third goal parameters." END_FIELD FIELD plan_window TYPE R4 DESCRIPTION "This is the weight of the sixth goal parameter used by the CALENDAR/AUTO program to schedule SUs. The goal is to schedule SUs in plan windows." END_FIELD FIELD prio_thresh TYPE I2 DESCRIPTION "This is a threshold on SU priority. The CALENDAR/DELCAND program will issue a warning message and then query the user about the deletion of any scheduled SU with a priority above this threshold. The /NOWARN option on CALENDAR/DELCAND will cause an SU with a priority above the threshold to be deleted without warning." END_FIELD FIELD high_thresh TYPE I2 DESCRIPTION "This is a threshold on SU candidates priority. Candidates with a priority above this threshold are considered to be high priority by the scheduling software." END_FIELD FIELD med_thresh TYPE I2 DESCRIPTION "This is a threshold on SU candidates priority. Candidates with a priority above this threshold are considered to be medium priority by the scheduling software." END_FIELD FIELD dog_pt_mult TYPE R8 DESCRIPTION "This is a value used in the calculation of a dogleg maneuver which results in a pointing which lies outside of the solar constraint region." END_FIELD FIELD max_si_nodes TYPE I4 DESCRIPTION "This is a value used by the scheduling software as a means to limit processing when scheduling SI activities. The combinatorial state transition tree formed by the software contains all possible sequences that can be attempted to bring an instrument to a required state. By limiting the number of nodes that the software will visit, this value will control processing time if the tree becomes excessively large." END_FIELD FIELD max_si_seq TYPE I4 DESCRIPTION "This is a value used by the scheduling software as a means to limit processing when scheduling SI activities. The software will stop scheduling SI sequences if the number of successful sequences processed is equal to this value. The sequence considered most optimal up to this point will then be used." END_FIELD FIELD bou_buf_1 TYPE SOGS_INT_TIME_TYPE DESCRIPTION "This is the duration of the interval after the calendar begin boundary where no activities can be scheduled. " END_FIELD FIELD bou_buf_2 TYPE SOGS_INT_TIME_TYPE DESCRIPTION "This is the duration of the interval before the calendar end boundary where no activities can be scheduled. " END_FIELD FIELD aln_shad_pad1 TYPE SOGS_INT_TIME_TYPE DESCRIPTION "This is a time pad which controls how close an alignment can schedule before the HST crosses the earth shadow boundary. This applies to either entering or exiting the shadow. This pad is only used if the alignment shadow flag in relation 'qalignment' is set to 'C'." RELATED_FIELDS "qalignment.shadow" END_FIELD FIELD aln_shad_pad2 TYPE SOGS_INT_TIME_TYPE DESCRIPTION "This is a time pad which controls how close an alignment can schedule after the HST crosses the earth shadow boundary. This applies to either entering or exiting the shadow. This pad is only used if the alignment shadow flag in relation 'qalignment' is set to 'C'." RELATED_FIELDS "qalignment.shadow" END_FIELD FIELD latesch_inst TYPE SOGS_INT_TIME_TYPE DESCRIPTION "This is the initial bisection method step size used in the calculation of the latest obset start time. This value is used during the 'late scheduling' phase of SU scheduling." END_FIELD FIELD latesch_mnst TYPE SOGS_INT_TIME_TYPE DESCRIPTION "This is the minimum bisection method step size used in the calculation of the latest obset start time. This value is used during the 'late scheduling' phase of SU scheduling." END_FIELD FIELD par_delta TYPE SOGS_INT_TIME_TYPE DESCRIPTION "This is the time delta which controls how close unattached parallel SUs are scheduled next to each other." END_FIELD END_RECORD RELATION wgtune_parms TYPE WGTUNE_TYPE DESCRIPTION "Default Tuneable Scheduling Parameters Relation" SUBSYSTEM_USING "SPSS", "CCLIST", "SCIOPSDB" INDEX wgtune_parms_1 TYPE clustered FIELDS max_sci_rtrn END_INDEX END_RELATION INSTANCE wgtune_parms GLOBAL TYPE WGTUNE_TYPE END_INSTANCE
