Relation between distance estimates using Gaia parallax DGaia (Bailer-Jones et al. 2018), spectral type-luminosity DSpL, and the Ca II H, K doublet, DCa II. Squares (grey) represent the Ca II distances by Megier et al. (2009), and circles indicate the distances as listed in Table 3, with sightlines dominated by single-cloud (orange), multiple clouds (green), cold (blue), and warm (red) clouds, as labelled.
