Make this plot go from -1.2 to 0.5 arcsec. There is nothing to be seen in the other region. Position velocity diagrams for subtracted image of UY Aur; The x-axis shows the velocity with respect to the feature rest wavelength in the velocity frame of the star UY Aur A (?) and the y-axis the distance along the slit.  The emission from the two stars has been removed and only the resolved emission can be seen. In the left panel, resolved emission is visible around  \(-100\ \mathrm{km\ s^{-1}}\) .
