Goals
The overall goal is to complete the commissioning of the polarization capabilities of the NIKA2 camera, and make the first steps towards Science Verification. Following the data and their analysis from December 2018 and Feb 2020, the main priorities are:
- Confirmation of absolute angle calibration: on 3C286 + another QSO (chosen closer to dates depending on brightness/pol) also with XPOL observations, and on MWC349 (versus NOEMA?)
- XPOL sessions with Ioannis/Albrecht on 3C286 7h-9h on Thursday. If possible shared XPOL/NIKA2 on another QSO (3C454.3?) on Thursday evening ? - will adapt depending on weather/local conditions
- Stability of angle measurements and error bars with deep integrations on polarization standards, eg OMC1/DR21/Crab
- Evolution of Stokes Q/U rms with time with long integrations on known faint/extended sources to confirm tentative NEFDs obtained so far
- the two previous items will also allow to test our decorrelation methods developed for map-making on extended emission
- Get maps of polarization "leakages" using planets (Uranus) every night to evaluate the precision of correction in « real-conditions »

Observers and Schedule
Due to the Covid pandemic there's no travel at the telescope, observations will be on remote with the help of the remote AOD and Operators at the telescope. List of the remote observers and the shifts we agreed on:
3shifts of two people as follows (all times local time ie UTC+1h) :
-- 18h-23h30: Philippe + Hamza
-- 23h-4h30: Juan + Samuel (except night Sun15-Mon16 = Alessia takes Juan shift)
-- 4h-9h: Nicolas + Anaëlle
+ Daily meetings on zoom at 4pm.
Ioannis/Bilal are the AoD, see IRAM's http://www.iram.es/IRAMES/mainWiki/AstronomersOnDutySchedule.
