Per SIS Instrument Team direction, the FOT will disable the following 6 strips: M1AHV #29, 36, 48 and M1BHV #20, 24, 27. If there is no improvement in the RTSW rates during the pass, the FOT will disable 2 more strips: M1AGND #19 and M1BHV #42. Note: The current plan is to implement SIS OCR-65 during the DOY 357 DSS-15 contact (BOT=20:30 UT). ======================================================================== Activities: Data Capture: 100% DOY 347-354 2015 ======================================================================== Anomalies: None
