Extended Data Fig. 7: Rotated Stokes plane.
From: An asymmetric electron-scattering photosphere around optical tidal disruption events
The data from Fig. 3 is shown after rotating anti-clockwise so that qrot becomes parallel to the dominant axis. As no reliable fit was obtained for AT 2019dsg, this TDE is not shown on the rotated Stokes plane. We note that the pre-maximum data of AT 2018dyb shows a large systematic offset from urot = 0, while the data at + 50 days only shows some scatter around this axis. All error bars are 1σ uncertainties. All data is shown here after correcting for the ISP and for the host dilution.
