MODIS IOT Terra Weekly Report
Mission Operations Days: 2002/320 to 2002/326
November 15, 2002 20:00:00 GMT to November 22, 2002 20:00:00 GMT
On Monday, November 18, 2002 (DOY 322), 2 one word patches were loaded to the CP07 table onboard MODIS. These patches were
put in place so that when transitioning to OUTGAS mode or SCIENCE mode, formatter B would be used instead of formatter A.
