Notes. τ9.7 is the simple conversion from AV to the optical depth of the Si feature based on the κ(λ) curve from Schartmann et al. (2005) and is included only for comparison to previous results, namely T14. Projected distances in parsec are given from the central aperture, D0, with Circinus 4.2 Mpc away (Freeman et al. 1977). We measure the inclination to be i ≳ 83°, so the correction from projected to physical distance is small. The two rightmost columns are the results of re-fitting with a Gaussian prior on AV = 28.5 ± 8.1, based on the initial fit to D0. Aperture D0 was fitted only once, and its fitted AV value (in bold) is used as a prior in the second iteration of all other apertures.
