UNIFIED CATALOGUE OF CLASS II METHANOL MASERS AT 6 GHz
Abstract:In this paper we present a unified catalogue which contains published data about class II methanol masers at 6 GHz. Our catalogue contains information about 495 maser sources. The data on some parameters of emission in "quasi-thermal" molecular lines CS(2-1) and SiO(2-1) is also included in our catalogue.
Using the unified catalogue we studied correlations between some parameters of the sources. Analysis of the data shows the following: physical conditions within the usual maser source vary considerably; maser brightness is determined by parameters of some distinguished part of the object - maser formation region; class II methanol masers are formed not in the shocks but in the regions affected by their propagation.
