Notes. Single Tau A observation conducted on 30 November 2021. The upper part lists the scan parameters, while the lower part reports polarization efficiency (η) and responsivity (ℜ) for each channel (CH). We chose this scan as it showed one of the lowest noise estimates of our sample, and it was close in time to the Moon observations from Section 4.2. Additional scans are included in the monthly coadded analysis presented in Table 5 and will be further discussed in Fernández-Torreiro et al., (in prep.).
