Dust absorption opacities using the dust grain compositions DSHARP Birnstiel et al. (2018), DIANA Woitke et al. (2016) and the composition mentioned in Dullemond et al. (2022) (refered to as D22 in the plot). The black dashed line shows the absorption opacity for the default opTool grain size distribution, and each grain consists purely of pyroxene. The vertical bars indicate the wavelength range of different ALMA bands. The mean absorption opacity for each band is calculated based on the DSHARP composition.
