Top: Extinction map of the local ISM viewed top-down taken from Dharmawardena et al. (2024). The Sun (yellow circle) is at X, Y = 0, 0 and the Galactic centre is at X, Y = 8.2, 0 kpc. The twelve targets (cf. Table 1) are represented by colored stars. The two stars analyzed in this paper are shown in red and the other ten are shown in blue. The small gray star near the center of this figure indicates 10 Lac (AV = 0.21 mag), which was used as a reference star. The contours represent extinction in steps of 0.2 mag. Bottom: Dust map of the Milky Way galactic plane derived from Gaia photometry (see Andrae et al. (2023) for more details) with the twelve targets following the same color scheme as above. Note that some of the targets overlap in this projection. -- astro-ph.GA
