Simulated synthetic spectra for HNC and HCN lines

Data used in the paper "Unmasking the physical information inherent to interstellar spectral line profiles with Machine Learning I. Application of LTE to HCN and HNC transitions", published by A&A Magazine.

The files contain a set of simulations performed under typical physical conditions found in dense molecular clouds and star-forming regions. Each file includes simulations for five spectral transitions of HCN and five of HNC, corresponding to rotational transitions J=1–0 (~90 GHz), J=2–1 (~180 GHz), J=3–2 (~270 GHz), J=4–3 (~360 GHz), and J=5–4 (~450 GHz). The models explore a parameter space that includes temperatures ranging from 5 K to 150 K in steps of 5 K, HNC/HCN abundance ratios from 0.1 to 1.0 in steps of 0.1, source sizes from 1 to 6 arcseconds in 1 arcsecond intervals, and line widths (∆Vsys) from 1 to 19 km s⁻¹ in 1 km s⁻¹ increments. All simulations were performed considering an LTE model.
