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
