Comparisons of Stokes I, linear polarization, and EVPA (top, center, and bottom rows, respectively) for the four calibrators in this track using AMAPOLA (ALMA, black dots) and SMA (calibrated through COMPASS and CASA, red crosses) during 2024, showing that the calibrator properties are consistent with each other. The rms-based error bars for SMA are plotted but smaller than the marker size.
