Notes. The distances were taken from the catalogue of Astraatmadja & Bailer-Jones (2016) and we used the values for a scale length, L = 0.11 kpc. We also give the distance estimates prior to Gaia where available, the observed optical brightness range in the V-band determined from AAVSO data spanning the period 1995–2015 (apart from the three old novae), and the range in absolute magnitude MV implied by the TGAS distances. We determine X-ray luminosities using the TGAS distance and X-ray flux compiled from the literature or from an analysis of Swift data.
