Midplane gas temperatures in the low and moderate optical depth static disk RT benchmarks (following Pascucci et al. 2004). Top: temperature as a function of radius as determined by RADMC as well as both grey and frequency-dependent results as determined by AZEuS. Bottom: relative difference between AZEuS and RADMC results. We note that the RADMC and AZEuS grid points are not co-spatial, and so the RADMC data is linearly interpolated to the location of AZEuS zones as necessary.
