The various anomalies associated with the T2 thermocouple, like its
disconnect from the Pout, may be explained by the close distance, a
few cm, of the internal fins to the lid. The T2 thermocouple rod,
which protrudes down through a fitting in the lid, may be long enough
to reach the fins.
Dennis Cravens noted that RF affects thermocouples. They rectify the
signal. This has been observed in CF experiments. This would mean
the RF signal could bias T2 upwards during the heat after death period.
