Context. Modeling of atomic and molecular processes in the interstellar medium, especially in the case of nonlocal thermodynamic equilibrium requires combining spectroscopic and collisional data. This combination provides a so-called matching file that is an input file for radiative transfer codes.
Aims. We present the main functionalities of the SPECTCOL software that was developed in the environment of VAMDC standards: retrieving and exporting information from the CDMS, JPL, or HITRAN spectroscopic databases and the BASECOL collisional database, combining spectroscopic data and collisional data, and exporting the matching result in various formats.
Methods. The SPECTCOL software is a Java client.
Results. All molecules in the BASECOL database were tested with the SPECTCOL software, and the resulting matching files are available in a repository.
Conclusions. The SPECTCOL software and associated tutorials are available on the VAMDC website.
Key words: standards / astrochemistry / molecular data / radiative transfer / virtual observatory tools
