Top: comparative Swift/XRT light curves of RS Oph 2006 (cross) and T Pyx 2011 (dot) until day 200 after outburst for both. Bottom: hardness ratio showing that the supersoft phase was not seen for the T Pyx observations, the optical depth in the soft XRs completely obscured the white dwarf (see text for discussion). The H/S ratio for T Pyx used (0.8–10 keV)/(0.3–0.8 keV). For RS Oph we used the data in Schwarz et al. (2011) with the H/S ratio defined by (1–10 keV)/(0.3–1 keV).
