RECORD INFORMATION ! !------------------------------------------------------------------------------ DESCRIPTION "This relation is used to define Science Instrument (SI) and SI Detector state transitions. A transition is a method in which an SI or Detector can change its mode or configuration. For example, suppose that there is an SI on board the HST. There are 3 modes for this instrument: HOLD, WARM, and CAPTURE. A typical user will want to operate the SI in the CAPTURE mode while observing a target. At a minimum, the SI must transition thru the WARM mode prior to transitioning up to the CAPTURE mode. Entries within this relation will have to be defined that describe the attributes of: o changing from the HOLD state to the WARM state (and vice versa) o changing from the WARM state to the CAPTURE state (and vice versa) There are many attributes that describe a transition, including: o the power needed to transition into the next state o how long the transition takes o is there a warmup or cooldown duration associated with the transition? o are there external constraints (SAA, occultation) that can interfere with the transition o the previous and next states of the transition o etc..." !------------------------------------------------------------------------------ ! ! FIELD INFORMATION ! !------------------------------------------------------------------------------ FIELD si_name TYPE SI_ID_TYPE END_FIELD FIELD si_det_name TYPE SI_DETECTOR_TYPE DESCRIPTION "This field is blank for SI states. By being blank, it actually designates that this transition is for an SI." END_FIELD FIELD prev_state TYPE SI_CONFIG_STATE_TYPE DESCRIPTION "This field is the name of the state at the start of the transition." END_FIELD FIELD next_state TYPE SI_CONFIG_STATE_TYPE DESCRIPTION "This field is the name of the state at the end of the transition." END_FIELD FIELD trans_type TYPE C1 DESCRIPTION "This field is a flag indicating whether this transition is an upward or downward transition." DISCRETE "U", "D" END_FIELD FIELD command_time TYPE I4 DESCRIPTION "This field is the amount of time used to command to the configuration." UNITS "SECONDS" END_FIELD FIELD min_warmup TYPE I4 DESCRIPTION "This field is the minimum warmup period duration for upward transitions. This field is not applicable for downward transitions. See System Engineering SI User's Guide for more information concerning this field." UNITS "SECONDS" END_FIELD FIELD min_time_req TYPE I4 DESCRIPTION "This field is the time required in the previous lower state for minimum warmup duration for an upward transition. This field is not applicable for downward transitions." UNITS "SECONDS" END_FIELD FIELD max_warmup TYPE I4 DESCRIPTION "This field is the maximum warmup period duration for upward transitions. The value must not be less than the minimum warmup duration. This field is not applicable for downward transitions." UNITS "SECONDS" END_FIELD FIELD max_time_req TYPE I4 DESCRIPTION "This field is the time required in the previous lower state for maximum warmup duration for upward transitions. The value must not be less than the time required for minimum warmup duration. This field is not applicable for downward transitions." UNITS "SECONDS" END_FIELD FIELD cooldwn_time TYPE I4 DESCRIPTION "This field is the cooldown time required for downward transitions. This field is not applicable for upward transitions." UNITS "SECONDS" END_FIELD FIELD parallel TYPE YES_NO_FLAG_TYPE DESCRIPTION "This field specifies whether a transition activity may be scheduled in parallel with the warmup or cooldown period of this transition. If specified for an SI transition, then the transition activities for its SI detectors may be scheduled in parallel with the warmup or cooldown period following this SI transition. If specified for an SI detector transition, then the next SI transition activity for the SI may be scheduled in parallel with the warmup or cooldown period following this SI detector transition. Note that this field only applies to a SI GROUP (an SI and its Detectors)." END_FIELD FIELD power TYPE I2 DESCRIPTION "This field is the power required for the transition. SI transitions and states must schedule according to HST power availability/constraints." UNITS "WATTS" END_FIELD FIELD power_delay TYPE YES_NO_FLAG_TYPE DESCRIPTION "If this field is set to 'Y', the power required during the warmup or cooldown period is the power required during the SI reconfiguration activity. Otherwise, the power required is the power for the next SI or Detector state." END_FIELD FIELD saa_flag TYPE YES_NO_FLAG_TYPE DESCRIPTION "This field is a flag indicating whether the transition is allowed during the SAA." END_FIELD FIELD saa_model TYPE SAA_MODEL_TYPE DESCRIPTION "This field is the SAA model id for the transition. This field is set only if the transition is not allowed in SAA, as determined by the saa_flag field." RELATED_FIELDS "wsistate_tra.saa_flag" END_FIELD FIELD saa_recovery TYPE I4 DESCRIPTION "This field specifies the recovery time after SAA exit before the transition is allowed. This field is set only if the transition is not allowed in the SAA, as determined by the saa_flag field." UNITS "SECONDS" RELATED_FIELDS "wsistate_tra.saa_flag" "wsistate_tra.saa_model" END_FIELD FIELD motion TYPE YES_NO_FLAG_TYPE DESCRIPTION "This field specifies whether the mechanism motion flag is set during the transition. Transitions setting this flag cannot be scheduled within an observation set that disallows the flag to be set." END_FIELD FIELD nssc1_used TYPE YES_NO_FLAG_TYPE DESCRIPTION "This field is a flag specifiying if the NSSC-1 scratch pad is used anywhere during this transition." END_FIELD FIELD command_code TYPE C8 DESCRIPTION "This field is a reference to the change code used to identify the instruction which is expanded to generate commands for the transition." RELATED_FIELDS "qgreconfig.change_code" END_FIELD FIELD penalty TYPE I2 DESCRIPTION "This field specifies the component of the penalty which results when the transition must be scheduled. This penalty is used by CALENDAR/AUTO." END_FIELD FIELD trans_prio TYPE I2 DESCRIPTION "This field specifies the priority of this transition when the scheduling software selects the next SI activity to process and several choices exist. See System Engineering SI User's Guide for more information concerning this field." END_FIELD FIELD trans_order TYPE I2 DESCRIPTION "This field specifies the order of this transition when the scheduling software selects the next SI activity to process and several choices exist with the same priority." END_FIELD FIELD pdb_record TYPE I4 DESCRIPTION "This field is the PDB record number. This field is currently unused, and set to 0." END_FIELD FIELD comments TYPE C80 DESCRIPTION "This field is descriptive text describing this state transition."
