Back to list of day to day logbook of observations

2014-01-23

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.

Normally TAPA should work with all scan, we keep a simplified table below for now as a safety.

Programm for today:

Focus and Beam maps (standard + Lissajou). Centered on the refence detector: #494 of the 2mm array (#5 of the 1mm array is very close to it).
Pointing session
Skydip
Mount polariser, take OTF and Skydip with it (Andrea has left, last day of Nicols, so necessary to test polar scripts today).

OFFSET -37 -30 /sys Nasmyth => select detector 494 as reference

Scan	UT	Source	Command	Pointing X,Y, Focus	Comment
112	15h20	Uranus	Track -200 -200	0,0, -1.4	usefull to 1st tune of resonances. OFFSET -37 -30 /sys Nasmyth
113	15h24	Uranus	pointliss	0,0, -1.4
114	15h25	Uranus	cross	0,0, -1.4
115-119	15h26	Uranus	focusliss	0,0, -1.4
120	15h30	Uranus	focusp	0,0, -1.4

 Line 13:
- * 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).

- * Polariser on, and test observations with polariser: beam maps (+pointing and focus of course) first on planet then on a polarised source.
