The bias value, readout noise, gain, and in the future also the linearity are monitored by the Support Astronomers. SA, please update this table in any D nights and, if possible, also at the beginning of each observing run with a visiting astronomer. Report any anomalous value to the Operations Team via a Fault Report.
