Overview of the ALMA light curves of Sgr A* obtained in band 3 (left column) and band 6 (right column), each with four 2 GHz-wide sub-bands, spanning 85−101 GHz and 212−230 GHz, respectively. A significant reduction of the fractional polarization and an increase in the EVPA variability in the lower frequency band are visible.
