Left panel: color excess E(B−V) estimates for the 19 XMM field directions, colored according to the Galactic latitude: (i) integration in the local-reddening-inverted maps (solid lines); (ii) Pan-STARRS color excess at 400, 600, and 1000 pc from Green et al. (2015), rescaled values using measurements at 4 kpc and Planck τ-based E(B−V)s (see text). Colors refer to the Galactic latitude (inserted color scale) and markers are different for each direction. Some measurements are missing at shorter than 1 kpc because their uncertainty is too large). We also show the color excess values based on KI absorption lines for the NARVAL field stars in the NPS terminus region as a function of their Hipparcos distance ranges (black dots and error bars). The three targets that are located along the XMM path are indicated by large circles whose colors refer to the latitude. Right panel: XMM NPS fitted absorbing columns scaled to E(B−V) using N(H) = 3 to 5 × 1021 cm-2 mag-1.
