Same as Figure 11 but for the ﹩{\dot{M}}_{{\rm{in}}}=1{0}^{-7}\,{M}_{\odot }\,{{\rm{yr}}}^{-1}﹩ model. The streamer-induced signatures are more prominent and span a broader velocity range than in the ﹩{\dot{M}}_{{\rm{in}}}=1{0}^{-8}\,{M}_{\odot }\,{{\rm{yr}}}^{-1}﹩ model. The positive residuals in the outer disk (dotted–dashed) are also visible in the lower lobe, suggesting a stronger disk warp. Residuals are likewise present in the inner disk (R < 200 au); however, these features should be interpreted with caution, as this may arise from fitting the data cube with a Keplerian circular-disk model.
