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, and since MPPSync is dead, we will turn the HWP by hand when we start polarised observations.

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.
