Abstract
The article analyzes the quality of collections of experimental vibrational-rotational energy levels and transitions of the main isotopologue of the water molecule placed in the information system (IS) W@DIS. Software for automatic support of the quality of the collection of energy levels and transitions when loading new data sources was created. This software performs sequential double filtering using the latest version of empirical energy levels, as well as quasi-empirical energy levels. A brief description of the introduced quasi-empirical energy levels and their role in updating the quality of data is given. Statistical data on each of the collections are presented, subsets of collections suitable for decomposition of expert wave numbers and lower-level energies are distinguished.
