Results from VISAD pipeline. (a) Stokes V dynamic spectrum. (b, c) Band-averaged light curves in Stokes V and I. The ordinate shows T_B (left) and flux density (right), respectively. Different periods of activity are marked. Basal flux density levels in Stokes I and V are represented by dotted lines in the respective panels. We note that the T_B values are nominal and simply highlight that the emission is via a coherent emission mechanism. Since the true source sizes are unknown, an average (i.e. across the whole unresolved stellar disc) T_B is computed here.
