Upper panel: parallaxes of sources which are in the TGAS catalogue and had previously determined parallaxes (the data measurements are outlined in Table 1). For SS Cyg there are four previous parallaxes. Lower panel: comparison of the distances of the 16 CVs in TGAS (taken from Astraatmadja & Bailer-Jones 2016, and tabulated in Table 2) with the best distance estimate pre-Gaia. We indicate by different symbols whether the pre-Gaia distance was determined via a parallax measurement or modelling spectra or colours. We note which system corresponds to which point by means of an abbreviation of the source name.
