This page gathers the information on the technical observations that are needed to perform NIKA2 calibration.
First version created on Mars. 7th by Hervé Aussel, F.-Xavier Désert, Jean-François Lestrade, Juan Macias-Pérez, Frédéric Mayet, Laurence Perotto & Nicolas Ponthieu.
Pointing
A full pointing session (20 to 30 sources) to be done on the first night. Let's use Samuel's excell file to check the coverage in elevation and azymuth.
Beammaps
Beammap sequences, which are focus + pointing + beammap, are to be done about once a day, spanning various elevation, at the best average focus (z central - 0.2 mm).
The best quality beammap should be achieved toward Mars when rising; You may consider also doing beammaps during the night toward 3C84 (as an alternative to planets, as none of them are visible at night for this campaign).
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.

Special beammap sequences
No special beammap tests are planned for this campaign as the Planet visibility is not favorable for testing subtle effects.
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 Uranus, which is NIKA2 primary calibrator: do a series of 2 OTF 8x5 scans, twice or 3 times a day
- Observe also Neptune and Mars using 2 8x5 OTF scans at constant elevation, twice a day
- Observe MWC349 during the day and LKHa101 at night, using the loop script comprizing 4 OTF scans, at least twice a day

Gain-elevation monitoring
For this run we prefer to concentrate on primary and secondary calibrators.
