| TAPAS is working properly | * TAPAS is working properly * Rely on TAPAS for most scan info (time, az, el, opacity) * Here, this wiki will inform in greater detail the PAKO command and quick analysis of scans (e.g. pointing results). |

| * 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 |
* Push to faint point sources * Re-assess KIDs every couple(?) of hours on a bright source * Observe faint extended objects (NGC1068, Crab Nebula?) * Have a great time |

Back to list of day to day logbook of observations
2015-10-24
IMPORTANT NOTES ON OBSERVING INFO
- TAPAS is working properly
- Rely on TAPAS for most scan info (time, az, el, opacity)
- Here, this wiki will inform in greater detail the PAKO command and quick analysis of scans (e.g. pointing results).
Data Repository: /home/nika2/NIKA/Data/run13_X/scan24_X
Goal of the session:
- Push to faint point sources
- Re-assess KIDs every couple(?) of hours on a bright source
- Observe faint extended objects (NGC1068, Crab Nebula?)
- Have a great time
