NOTE: The SCIABNORM Flag was NOT set during the four calibration slews on Thursday, April 13th. The data during the maneuvers is invalid. In addition, during the +10 degree roll (first maneuver), the temperature of the cold focal planes increased approximately 0.5K and took about 4 hours to return to nominal temperature.
