Following not updated
TAPAS is working properly
Data Repository: /home/nika2/NIKA/Data/run13_X/scan24_X
Goal of the session:
- OTF geometry and beam map on Uranus: DONE
- check pointing on faint sources (pako pointing f and pointing l): Done pointing l, rta can't reduce pointing f
- Secondary calibrators and QSO with various spectral slopes according to iram monitoring: started
- Mars again
