We would like to correct an error in the position angle reported by Boley et al. (2012) for the disk model of the massive young stellar object AFGL 4176. The error arose due to a problem with the angle conventions used, and had no influence on the modeling of the data. The correct position angle φ is related to the previously reported (incorrect) value φ′ by φ = 270°−φ′. After correcting for this error, the position angle φ of the disk we find is 112° east of north (the value we reported previously was 158°, and should be disregarded). Although none of the other derived parameters are affected by this error, we report this corrected value in order to facilitate an easy comparison with future spatially-resolved interferometric studies in the (sub-)mm and/or near-infrared ranges for this particular object. We include here corrected versions of Fig. 12 and Table 4, and apologize for any confusion which may have occurred.
