Back to list of day to day logbook of observations

2014-10-10

Opacity is measured with the new taumeter at 225 GHz

Nasmyth offsets : -19, 5.8

Set pointing : 0, 0

Set Focus : -2.4 mm

Quick description of the session: measure polarization of quasars at various elevations and planets to test our system and calibrate

Polarizer on, HWP on but not turning at session start

Data Repository: Raw_X9

Acquisition = 39.7 Hz

Observing account: t21

Remark after few scans: TAPAS is working now, we see the scans, but we continue the manual log just in case.

1-3	00h46	Uranus	Track off -200 -200	208	54	0,0,-2.4	0.2	Tuning. We started a bit late, the time that ice melts and sky clears !

5	00h56	Uranus	cross	213	53	0,0,-2.4	0.1	Problem processing the scan
