HCO+ (top) and H13CO+ (bottom) channel maps with a velocity resolution of 0.21 km s−1. The rms noise, σ, is 0.016 Jy beam−1 per channel in both maps and the emission is detected with a S/N of 25 and 7, respectively. The grey dashed contour shows the Keplerian mask used and the dotted white lines mark the major and minor axes of the disk.
