Data distribution of the profiles of the simulated spectral line J = 4–3 of HNC for the grid of physical parameters values. The top display shows the temperature mapping of the data while the bottom one shows the abundance ratio mapping. Both panels depict the HNC J = 4–3 line transition, from which the line intensity and linewidth, along with their associated error bars, are obtained for the semi-empirical data of Orion KL. These values are indicated by a green dot in each panel.
