Pixel 23 characterization comparison.
| Polarization efficiency [%] | ||||
|---|---|---|---|---|
| CH1 | CH2 | CH3 | CH4 | |
| Ground | 96.2 ± 0.3 | 91.9 ± 0.6 | 96.7 ± 0.3 | 94.6 ± 0.4 |
| Tau A | 91 ± 4 | 98 ± 4 | 97 ± 6 | 93 ± 6 |
| Moon | 89 ± 16 | 88 ± 16 | 91 ± 16 | 86 ± 15 |
| Polarization angle [deg] | ||||
| CH1 | CH2 | CH3 | CH4 | |
| Ground | 131.5 ± 0.3 | −11.7 ± 0.3 | 42.9 ± 0.3 | 78.8 ± 0.3 |
| Tau A | 132.0 ± 1.4 | −15.1 ± 1.3 | 48.7 ± 1.4 | 73.9 ± 1.5 |
| Moon | 127.2 ± 2.2 | −15.5 ± 2.5 | 38.9 ± 2.1 | 75.1 ± 1.7 |
Notes. The results are presented for each channel (CH) and are obtained with three methods (MFCI ground calibration and on-sky calibration with Tau A and with the Moon) for the polarization efficiency (top) and the polarization angle (bottom). Different columns correspond to the different channels of the TGI Pixel 23.
