T Pyx flickering. The two B-band light curves are from data tabulated in Schaefer et al. (1992). The durations of the two time series are 246 and 264 minutes and cover around 2.3 orbital periods each. This light curve is directly comparable with the average folded light curve displayed in Figure  42, which covers nearly the same time interval. The non-averaged light curve displays much normal flickering large enough to generally mask the average shape of the periodic modulation.
