Observational and modeling results.

Line RMS Flux Model flux
(mJy beam-1) (Jy km s-1) (Jy km s-1)

HCO+J = 4–3 11.3 18.7 ± 0.7 26.0
H13CO+J = 4–3 8.2 1.0 ± 0.2 1.4
DCO+J = 5–4 13.1 2.2 ± 0.4 1.7

Notes. Each species and transition is given along with the rms in emission-free channels with a velocity width of 0.4 km s-1. The third and fourth columns show the line flux integrated over the disk, and the flux of the adopted model.
