3.6 cm and 6 cm lightcurves of J1819+3845 on 26 January 2002. Typical uncertainties on the 120 s averages are about 4 mJy for 3.6 cm and 1 mJy for 6 cm. This does not include systematic flux calibration errors, which we estimate at 4% for 3.6 cm and 2% for 6 cm. There appears to be a systematic time delay of about 10 min between the peaks of the scintles, with the 6 cm scintles lagging. In addition there appears to be a systematic asymmetry in the profiles near the peak, similar to that seen on many other occasions, see e.g. Fig. 11.
