Mollweide projection of the Galactic foreground reddening – E(B − V) – on the celestial sphere from the Planck Collaboration XLVII (2016) generated using the dustmaps Python package (Green 2018). The coordinates of each of the EAFs are indicated with black squares, and the EDFs are highlighted with red stars. The solid blue line shows the ecliptic. The dotted blue lines indicate the continuous viewing zone for the Euclid mission at $\pm 87\stackrel{°}{.}5$. The dot-dashed blue lines indicate ecliptic latitudes of ±54°, which is the expected boundary for the continuous viewing zone of the Roman space telescope (Foley et al. 2018). The dashed blue lines show the continuous viewing zone for JWST at ±85°. The locations of the north and south ecliptic poles are indicated with the text NEP and SEP, respectively.
