Evolution of the temperature of the SODISM flight CCD. After the cooldown period in July 2010, the CCD was first regulated at −11 °C for a month and a half. Because it was anticipated that this temperature could not be maintained for the whole duration of the mission, the setup point was subsequently raised to −7.2 °C in mid September 2010. The short- and long-term stabilities around that point are on the order of ± 0.1 °C peak-to-peak (P-P). The precision of the measurement is 2 mK, viz. a hundredth of the amplitude of the residual variation. Two bakeout periods occurred on 15–18 June 2011 and on 13–17 June 2012. They allowed heating the CCD up to 21 °C for two days, and up to 24 °C for three days, respectively. Brief stages can be noticed during their warmup and cool-down phases.
