The line_2: present exercise establishes the performance characteristics associated with line_3: reducing the temperature to 13 degrees C. This should lead to a reduction in line_4: power consumption and improved performance. line_6: Revised 9/15/89 & 11/16/89 to match Implementation Plan. line_7: 12/14/89 ! ! end of abstract general_form_proposers: lname: LAURANCE fname: ROBIN mi: J inst: ESA/FOC country: HOLLAND esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 0 line_1: The purpose of the exercise is to examine the performance characteristics of line_2: operating the FOC with the Optical Bench Enclosure at 13d C instead of the line_3: present baseline of 17d C. Whilst the instrument is in Hold Mode the thermal line_4: control tables should be modified to achieve the 13d C set points. Thirty-six line_5: hours should then be allowed to achieve thermal stability prior to taking the line_6: exposures necessary to determine the instruments's new characteristics. line_8: Finally, the Thermal Control set points will be returned to 17 degrees C and line_9: followed by 36 hour wait for thermal stabilization. ! question: 5 section: 0 line_1: line_2: FOC should be transitioned from HV ON mode (when applicable) to STANDBY mode line_3: during SAA passage. line_5: FOC012 (ID 1497) must be successfully completed before initiating this test. line_7: Wait 36H after execution of this procedure for Thermal Stabilization before line_8: scheduling next FOC Test. ! !end of general form text general_form_address: lname: LAURANCE fname: ROBIN mi: J. category: PI inst: ESA/ESTEC addr_1: POSTBUS 299 city: NOORDWIJK NL2200 AG country: HOLLAND telex: 39098 ! ! end of general_form_address records !
