Daily Reports
Bilal, Charlene, Caroline, Iacopo, Florian, Stefano, Carsten arrive at the 30m. Full house.
Four shifts this time:
Afternoon: Charlene and Caroline
Evening: Bilal
Night: Florian and Iacopo
Morning: Carsten and Stefano
Last week, as NIKA2 was cold already, a frequency sweep was done at 1mm, and the pulse tube had been realigned by JLS, after notification by Martino who had seen indications of a spike at 0.3Hz.

- 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.
Night shift: Alternating NIKA2SZ and N2CLS COSMOS. Tau very stable, slowly degrading.
Jan 15, Wednesday
Morning shift: Continuing with N2CLS GOODS-North. Pointing, focus, tau stable. tau225=0.2 @ 05:30 UT.
