Blow-up column density views of the X-shaped nebula region in the California MC. Panel A: filtered version of the high-resolution (18.2″) column density map, showing partially-reconstructed filaments with transverse angular scales only up to ~ 100″ from getfilaments (cf. Sect. 2.4.3 in Men’shchikov 2013). The background image shows field stars from the Pan-STARRS optical survey (Chambers et al. 2016). Panel B: unfiltered high-resolution column density map with the network of filamentary structures identified by getfilaments overlaid in white. The crests of the ten filaments selected in Sect. 3.2 are highlighted in black and magenta for thermally supercritical filaments with M_line >M_line,crit and subcritical filaments with M_line < M_line,crit, respectively.
