Back to the NIKA2 2nd Science pool

This page gather the information on the technical observations that are needed to perform NIKA2 calibration.

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.

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:
