Line 12: Line 13:
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).
Line 19: Line 22:
 * 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

NIKA October 24, 2015 / S8

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
