2-fit results obtained from the RADEX simulations of the excitation conditions of the molecular gas. Four different [HCN]/[HCO
+] abundance ratios around the standard Galactic value of [HCN]/[HCO
+]
10 for three different HCN column densities are shown. The middle panel shows the best χ
2 fit found for each abundance ratio.
