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
