Bilal, Charlene, Caroline, Iacopo, Florian, Stefano, Carsten arrive at the 30m. Full house.

Jan 14, Tuesday

Laser used to check alignment between elevation axis and cryostat window. Strangely enough this seems to depend slightly on elevation. Small correction applied to M5 by SN.
Starting at 14:30 UT. High overcast of ice clouds.
Pointing session with ~33 sources (scans 237-269). Pointing offsets look OK. JP fits model. Fit of Nasmyth offsets leads to a very slight improvement from 1.9" rms to 1.7" rms. Not yet implemented. Beam widths look OK.
Secondary calibrators MWC349, NGC7027, CRL2688. Fluxes look OK.
Skydip
Beam map on Uranus at 50deg Elevation.
Central pixel lost. Hole in the 2mm array. Re-do tuning. Re-do pointing, focus, 2 beam maps to create new RPPs/kidpars after 1mm sweep done last week (scans 292 and 293).
tau225~0.14 and very stable. Forecast is good for the next two days. Ready to go. It would be helpful to have beam maps IMBfits be created separately from pointing and focus scans.
18:10 Finally, after 3.5 hours, starting with science: NIKA2SZ. New pointing model implemented in-between scans.
Alternating with N2CLS. Tau very stable, slowly degrading.

Continuing with N2CLS GOODS-North. Pointing, focus, tau stable. tau225=0.2 @ 05:30.
