All the people who will participate to the pool run must appear in the table below; each one must inform Samuel and contact Esther to reserve rooms in Granada and at the telescope. For those who travel on IRAM funds, Beatrice should be contacted; see the [[http://www.iram.fr/wiki/nika2/index.php/Travel_rules|NIKA2 travel rules]].

Staffing of the run in November 2017: table of the nights spent at the observatory for the NIKA2 collaboration members participating to the run (T = Tuesday, S = Saturday, 1 = night scheduled at the telescope, g = night in Granada office). <<BR>>

== List of tests/checks to be carried out ==



Beammap in TP

Get NOEMA and XPol polarization for QSOs


QSO maps at different elevations, 

Maps of Mars (day) + maps of Uranus (night) at different elevations

Polarized skydips

Empty fields deep integration : check evolution of noise with time + check HWP subtraction holds + check leakage effects

Empty field with only one compact source (weak, but polarized)

Test various speeds for HWP rotation / acquisition rate tests

Large / fast scanning map with weak/no source

If time: Crab and standard candles for polarization (OMC1, B335)



Offline: 
Work on HWP subtraction
-- Characterize beam leakage + instrumental leakage
-- Angle calibration from QSO versus XPOL
-- (p,phi) estimators
-- Transfer function
-- Comparison to polarized simulations
