Dynamic spectrum formed from images of CR Dra for the 2014-06-02 epoch in total intensity. The median noise in each image used to form this dynamic spectrum is 1.7 mJy, with ≈25% of the pixels corresponding to a ≥3σ detection. The burst in the upper-left saturates at ≈40 mJy. The colour bar at the bottom communicates the flux density scale in mJy. The white bar centred around ≈150 MHz correspondsto the frequency range for which radio frequency interference prevented reliable data being recovered. Top and righthand panels: lightcurve and spectrum of CR Dra if integrating completely over bandwidth and duration, respectively.For high signal-to-noise areas, the flux density is represented with a line that has uncertainty to better than 10%. These two side plots show that CR Dra is detected at all times and at all frequencies.
