Back to list of day to day logbook of observations

2014-01-23

We use both the manual log below and the tapas database that automatically fills scans table with the scan informations.
So please login with the t21 acount and its usual password (durc***9) to the TAPAS database.
Yesterday's scan are all in TAPAS (inserted by hand), but the auto fill problem is still there, so in real time we only see the Lissajous. So we keep a manual log below, but in a simplified table with the comments and only the most useful scan info.

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	Tau 0.1 !!
114	15h25	Uranus	cross	0, 0, -1.4	problems in the data
115-119	15h26	Uranus	focusliss	0, 0, -1.4	started the scan too quickly: tune didn't have time to follow
120	15h30	Uranus	cross	0, 0, -1.4
121	15h32	Uranus	focusp	0, 0, -1.4	a problem to fix in the pipeline, take this debug time to do a frequency sweep, should not affect data, but several min without obs.
122	15h45	Uranus	track	0, 0, -1.4	a problem to fix in the pipeline
123	15h45	Uranus	otfgeom	0, 0, -1.4	((can't run make imbfits for now, will do when pipeline ok))
124-128	16h20	Uranus	focusliss	0, 0, -0.8
129	16h22	Uranus	pointliss	0, 0, -0.8
130	16h22	Uranus	pointliss	-6,-5, -0.8
131	16h31	Uranus	focusliss	-6,-5, -0.8

- * 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.
