Quick description of the session: Beammaps for statistics at different foci
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 cryostat level (9 mm) and therefore use the old pointing model.
Observers: Juan + Florian -- Operator: Quique

We start a new session (Juan, Florian, operator: Quique). We first want to do a large map on Mars to get the far side lobes. --> Pointing on the nearest quasar |
