Presently the GHRS line_4: is to be left in the side 2 HOLD mode (with low voltage line_5: turned on) at the end of the shuttle portion of the line_6: servicing mission. At this time the vac/ion gage and line_7: one bank of the DEB's will be on. This activity will line_8: consist of configuring side 2 to Low Voltage Engineering line_9: mode to reload and verify the detector 2 thresholds. line_10: Normal reconfiguration back to HOLD mode will leave the line_11: GHRS in standard HOLD. ! ! end of abstract general_form_proposers: lname: GILLILAND fname: RONALD mi: L. inst: ST SCI country: USA ! lname: SODERBLOM fname: DAVE inst: ST SCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The GHRS will be configured from Servicing Mission HOLD to line_2: Low Voltage Engineering mode on side 2. The detector 2 line_3: thresholds will be loaded then verified in telemetry. The line_4: instrument will be returned to standard HOLD using normal line_5: reconfiguration commanding. ! question: 5 section: 1 line_1: This activity must be the first activity for the GHRS line_2: after the shuttle portion of the servicing mission. It line_3: should be scheduled to occur outside of the SAA. HST line_4: engineering telemetry must be available in realtime during line_5: this activity so that telemetry pages may be snapped for line_7: threshold verification. line_9: This is an internal test and does not require any special line_10: pointing. ! !end of general form text general_form_address: lname: GILLILAND fname: RONALD mi: L category: PI inst: ST SCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! ! end of general_form_address records !
