Complete online database of the class I methanol masers

We present a database of class I methanol masers that contain information from the available literature and provides open and fast access to the data on class I methanol maser emission. The compiled information contains single-dish and interferometric data from published observations of class I methanol masers with detailed information about individual maser components from single-dish data and maser spots from interferometric data. At the moment the database contains information from∼100 papers, ∼6600 observations and∼700 source groups of class I methanol masers. Analysis of the data compiled in the database shows that the distribution of class I methanol maser sources is similar to that of class II methanol masers. They are mostly located in the Molecular Ring, where most of the OB stars are located. The difference between class I and II distributions is the presence of many class I methanol masers in the Central Molecular Zone. Access to the class I methanol maser database is available online at http://maserdb.net
