IRS 63 and L1709 B are often referred to as the same source (e.g., André & Montmerle 1994). However, L1709 B would appear to lie about 4 arcmin north of IRS 63 (e.g., Benson & Myers 1989). The source that Andrews & Williams (2007) refer to as L1709 B, is in fact IRS 63.

The opacity law quoted by Beckwith et al. (1990) is $\kappa_\nu = 0.1 \left( \nu/10^{12} ~{\rm Hz} \right) ^\beta$ for the gas and dust combined, implicitly assuming a gas-to-dust ratio $\Psi = 100$ , consistent with our work.
