Daily Reports
Observers on-site: Michael Mattern, Marie-Anne Carpine, Paul Law, Carsten Kramer and Stergios Amarantidis (AoD).
Operators: Gloria (day), Sergio (night).
All times are in Local Time.
Feb 18th, Tuesday
Maintenance: during maintenance CD tried to fix E1 (apparently the issue was found) and we conducted some tests with E0,1,2,3 (just tuning in some corresponding frequencies for each band).
15:00-22:00: Stergios: Basic training on NIKA2/EMIR observations. 15:00 LT: Wind gusts up to 20m/s thus we wait a couple of minutes for the weather to improve. At 16:21 LT we started with tuning with EMIR to project 143-24. Spindle errors and homology at scan 18, 19, 20, 21 (good start...). Operator moves in elevation manually. Now the plots are not appearing but the imbfits are created. Problem located, apparently we don't get the plots with the project account 'test', so we will observe with project poolw-24 for now. Under the poolw-24 account we get the calibration plots but not the pointing ones. Trying with the 143-24 project. It doesn't work (either a focus observation). JT was contacted, the operator restarted odp but still plots are not created. Apparently the chopper was in manual mode, we repeat a pointing test to see if we get the data and it works! Moving ahead with the observations.
Marie-Anne: Observing 143-24, mediocre conditions, we did calibrations on uranus, mars and 0458-020. We are observing NGC1977, map 4 vert. and then maps 1 to 4 horizontal. Spindle error but no scan lost (when changing project to test). Continuing with NGC1977 - project 143-24 (using the source 0430+052 for pointing; brightest source nearby) completing a forth repetition on the vertical maps. The weather though is quite unstable...
