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 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.
