Quick description of the session: Beammaps then secondary calibrator
We regulate at 205 mK and we are at 30% on the pump to be on the safe side. We solve the issue with the noise on the 2 mm array which was due to a misbehavior of the synthesizer: Martino told us to restart it and now the noise looks very good. Juan Penalver has provided a new pointing model.

We do a pointing a another source than Mars to avoid saturation of the detectors --> To faint for a good pointing --> We go on Neptune |
