Fig. A1.


YSO distribution and distance estimates toward Orion A, similar to Figs. 1 and 3. Additionally we show the positions of measured distances from the Literature. The gray band shows the distance of 414 ± 7 pc from Menten et al. (2007). Blue boxes are the reported distances from Kounkel et al. (2017; VLBA parallaxes). Green diamonds show distances to certain positions as given in Schlafly et al. (2014; optical reddening). The reported distances from previous works are largely in agreement with Gaia DR2 distances of YSOs, within the errors and the scatter. See also Table 1.
