Back to list of day to day logbook of observations

2014-01-22

Now we will use the tapas database that automatically fills scans table with the informations we were filling by hand untill now.

So please login with the t21 acount and its usual password (durc***9) to the TAPAS database.

Programm for today:

Check pointing and Nasmyth offset after re-alignment with the laser. Conclusion from yesterday: we don't have a reliable way to optimise the radio alignment, so we will rely only on the laser alignment, which seem very close to optimal according to 1st conclusions from yesterday.
Focus and Beam maps (standard + Lissajou).
Pointing session
Polariser on, and test observations with polariser: beam maps (+pointing and focus of course) first on planet then on a polarised source.
