Notes.

^(a)

ICRS coordinate system (J2000.0).

^(b)

When there are fluctuations in the lightcurve, two values of t₂ are given corresponding, respectively, to the first and last times the lightcurve falls by 2 mag from peak.

^(c)

The errors on the t₂ values are estimated by a bootstrapping algorithm (see text).

^(d)

Information about the spectroscopic types for the novae here is included whenever available (for details, see for example, Williams 1992; Shafter et al. 2011).
