Local ISM Properties from the γ-ray Analysis

	ROI A	ROI C
X CO a	$1.13\pm {0.08}_{-0.73}^{+0.20}\pm 0.10$	…
$\overline{R∕N(\mathrm{H})}$ b	$4.1\pm {0.3}_{-1.0}^{+0}\pm 0.3$	$3.2\pm {0.3}_{-1.0}^{+0.7}\pm 0.3$
$\overline{{\tau }_{353}∕N(\mathrm{H})}$ c	$2.06\pm {0.06}_{-0.65}^{+0.11}$	…

Note. No CO emission is detected in ROI C. The γ-ray scaling coefficients for the DNM maps derived from τ₃₅₃ in ROI C were always consistent with 0. The statistical uncertainties take into account the covariances of the fit parameters.
