Back to the NIKA2 2nd Science pool
This page gather the information on the technical observations that are needed to perform NIKA2 calibration.
Contents
Pointing
A full pointing session was executed on the two weeks ago giving good results. The pointings look stable and around zero now, so we won't redo a pointing session.
Beammaps
Beammap sequences, which are focus + pointing + beammap, are to be done at least once a day, spanning various elevation, at the best average focus (z central - 0.2 mm).
Beammap analysis status
The table below gathers the beammap scan ID, comments related either to the observing condition or to the reduced beammap quality and the analysis status
Status "done" means the analysis is completed, namely the kidpar file is produced using a 2-step iteration analysis, and uploaded in SVN.

Opacity
A skydip scan per 8-hour observation shift, in all possible weather conditions, is needed

Calibrators
- Monitor primary and secondary calibrators. Few of them but repeatedly along the run and at various elevation
- Observe in priority MWC349: use the loop script comprizing 4 OTF scans, 3 times a day
Observe also Uranus, Mars & Neptune + NGC7027 (and optionally CRL2688)
Below the visibility plot:
