SPHERICAL TOP DATA SYSTEM (STDS) SOFTWARE FOR THE SIMULATION OF SPHERICAL TOP SPECTRA

The Spherical Top Data System (STDS) software package for the simulati on of spherical top spectra is presented. It consists of a single UNIX script with self-explanatory arguments allowing the non-expert user t o calculate spectra from the results of the high resolution analyses p erformed over the recent decades on this type of molecules. More than one hundred parameter files are presently available including various band systems of 16 molecular species (among which methane is the most documented) and various types of calculations: rovibrational energy le vels, i.r. absorption, Raman scattering and Stark coefficients. STDS i s freely accessible by anonymous ftp at jupiter.u-bourgogne.fr. The ba sic instructions to get, install and execute STDS are explained. The c urrent status of the STDS content is described.
