Fig. 8.

Comparison of the observed column densities (blue line) with the modeled column densities by V17 (red line) and S16 (red dashed line) of CH3OH (left panel) and CH2DOH (right panel). The observed column density profiles are taken along the white dashed line shown in Fig. 2, being R = 0 au the dust peak, R > 0 au the direction from dust peak to methanol peak, and R < 0 au the direction from the dust peak toward the southwest. The shaded blue regions indicate the error bars of the column densities. The resolution is 30′′, shown at the bottom of the figure. A scaling factor has been applied to the models.
