Back to list of day to day logbook of observations

2014-10-09

Opacity is measured with the new taumeter at 225 GHz

Nasmyth offsets : 21.2, 36.75

Set pointing : 0, 0

Set Focus : -1.8 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_X35

Acquisition = 59,605 Hz

Observing account: t21
