Abstract

We have measured and analyzed the dark data of two PICNIC IR arrays (P574 and P560) obtained through the Cosmic Infrared Background ExpeRiment (CIBER). First, we identified three types of bad pixels: the cold, the hot, and the transient, which are figured in total as 0.06% for P574 and 0.19% for P560. Then, after the bad pixels were masked, we determined the dark noise to be 20.5 ± 0.05 e^- and 16.1 ± 0.05 e^-, and the dark current to be 0.6 ± 0.05 e^-/sec and 0.7 ± 0.05 e^-/sec for P574 and P560, respectively. Finally, we discussed glitches and readout modes for a future mission.
