It will be acquired with an Onboard line_2: Acquisition. A rapid readout observation will be started, with a sample time line_3: of 0.1 sec . Grating G160M will be used line_4: centered for Lambda=1550A. The observatrion will continue for 15 minutes. A line_5: second rapid readout observation will be started with a sample time of line_6: approximately 5 sec. It will be allowed to run for 30 minutes. The third line_7: exposure uses Accum mode, with intermediate data readouts after each line_8: pattern. This will give 10 sec time resolution for 30 minutes. line_9: The fourth exposure is a 20sec ACCUM mode observation which is line_10: repeated 90 times in 30 minutes. ! question: 5 section: 1 line_1: line_3: For time resolution faster than about 5 seconds than 4 kbps science link cannot line_4: be used. Idt will be necessary to use either the tape recorder or the 1.024 line_5: Mbps link for 15 minutes. line_7: The use of intermediate readouts will require that HRS be the only SI allowed line_8: to output data for the duration of the exposure. line_10: SV Minimum Plan: NONE line_11: SV Delta Plan: ALL - but high priority delta plan line_12: Guiding Tolerance: 0.025 arc seconds ! question: 6 section: 1 line_1: line_3: The purpose of the test is to verify the ability to obtain uninterrupted rapid line_4: readout observations, and to use intermediate readouts and repeat line_5: observations to maximize time resolution in Accum mode. ! question: 7 section: 1 line_1: The total number of spectra received will be counted, and their time tags line_2: inspected to verify that no data were lost, that the timing of the individual line_3: exposures was correct and that they are ordered in the correct sequence when line_4: made available to the GO. ! !end of general form text general_form_address: lname: HEAP fname: SALLY category: CON inst: NASA/GSFC addr_1: CODE 680 city: GREENBELT state: MD zip: 20771 country: USA phone: 301-344-5359 ! lname: CARPENTER fname: KENNETH category: CON inst: LASP/NASA-GSFC addr_1: GSFC city: GREENBELT state: MD zip: 20771 country: USA phone: 301-286-3453 ! lname: SAVAGE fname: BLAIR category: CON inst: DEPT.
