The 7.5 ms electron bulk velocity shows much improved agreement with E × B drift in the interval from 13:06:57 to 13:06:59 where we expect the electrons to be frozen in and strongly magnetized. (a–c) The 8 kHz EDP electric field at MMS2 averaged to 7.5 ms (black) and the FPI −V e×B/c at 30 ms (red) and 7.5 ms (green) resolutions. (d and e) The MMS2 FPI parallel and perpendicular electron pressure at 30 ms (red) and 7.5 ms (green).
