NIKA October 13th, 2014 / S5 [[D2DLogNika9 |Back to list of day to day logbook of observations]] == 2014-10-13 == ---- 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: [[https://tapas.iram.es/tapas/ | TAPAS]] is working now, we see the scans, but we continue the manual log just in case. ||'''Scan'''||'''UT'''|| '''Source''' ||'''Command''' ||'''Az'''||'''El'''||'''Pointing X, Y, Focus'''||'''Tau225'''|| '''Comment''' || || 1-3 || 00h46 || Uranus || Track off -200 -200 || 208 || 54 || 0,0,-2.4 || 0.2 || Tuning.
