Distribution of trap release-timescale values from the final three-trap species calibrations, calculated from the best-fit trap energy values of the calibration activity at epoch OBMT = 8224 revolutions. Three well-defined peaks for the different species of the CtiPixel model are present, including the fastest manufacturing species that dominated the CCD defects at launch and two slower radiation-induced traps. A tail of slower emission times can be observed for the third species. These can be interpreted as emerging defects still in an unstable configuration, similarly to the radiation-induced defects measured on board the Euclid mission CCDs.
