Guidelines to estimate observing times with NIKA2

%Guidelines to estimate observing times (Billot et al. 2014).

Python Script to estimate observing times.

To use the script, open a terminal in the same folder and type: 

   python time-estimator-IRAM30m-nika-gismo.py --camera "GISMO" --rms 0.5 --pwv 2 --elevation 30 --Xsize 4 --Ysize 6 --filtering 1.2 --overheads 2.0

where:

  • camera > IRAM 30m continuum camera. Options are GISMO, NIKA1mm, NIKA2mm.

  • rms > Any value above the confussion limit.

  • pwv > Precipitable water vapor. Possible values 2, 4, and 7 mm.

  • elevation > Values from 20 to 83 degrees.

  • Xsize Ysize > Mapping area. Xsize and Ysize must be equal (point sources) or larger than the Field of View.

  • filtering > Data filtering scheme. Values from 1 to 4.

  • overheads > Telescope/observing overheads (calibration, pointing, focus). Values from 1.6 to 2.6.
