Notes. The table includes precomputed partition functions (TIPS) with temperature (T) and Q(T), theoretical values such as transition branches, rotational quantum numbers (Jl), degeneracy factors (gl), and energy levels (El), as well as observed values including column densities (Nl) and their uncertainties (σNl). These inputs allow the package to perform spectral analysis using both the RD and χ2 fitting methods. The values provided in this table are pseudo data for 13C2D2, with even parity.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
