Time-series (Q1a; panel a) and integrated spectrum (Q1b; panel b) in Stokes-V (using |V′| as defined in Eqs. (9)–(11) of T19) for τ Boo during the observation L570725. Panel a: the ON-beam shows excess signal above both OFF beams at all times. Panel b: the signal inthe ON-beam is concentrated between 21 and 30 MHz and is distinctly different than in both OFF-beams. In both panels, the two OFF beams are equivalent within the error bars, calculated assuming pure Gaussian noise (). The dynamic spectrum for this signal can be found in Fig. 6. We find by performing Gaussian simulations that the probability to randomly reproduce the signal in the ON-beam curve in Q1a is 2.1 × 10−12 and 1 × 10−18 for Q1b. This probability corresponds to a statistically significant detection of 6.9σ and 8.6σ, respectively.
