Notes.
∗ indicates novae with parameters mainly from this paper while the remaining objects are from PHS2007 (their Table 8) and we give updated turn-off times, ejected masses and burned masses, + indicates novae confirmed by optical spectra;
maximum observed magnitude (not necessarily peak magnitude), “W” indicates unfiltered magnitude;
time in days the nova R magnitude needs to drop 2 mag below peak magnitude (see Payne-Gaposchkin 1964);
