Daily Reports

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. 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 kidpars after 1mm sweep done last week.
• tau225~0.1. 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: LPSZ. New pointing model implemented in-between scans.
