NIKA October 25, 2015 / S8

Back to list of day to day logbook of observations

2015-10-25

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
