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
