November Telescope Schedule 16h/day Observations.
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 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).

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
