STUDY OF THE EMISSION PROPERTIES OF CLASS II METHANOL MASER LINES
Parameters of the dependence between the intensities of the 51-60A+ (6.7 GHz) and 20-3−1E methanol maser lines are found: (logS6.7=0.8×logS12.2+0.8). In some maser condensations the ratio of the intensities of these lines differs significantly from this dependence. The interpretation was made that in these condensations an unknown factor acts to give additional amplification of the 51-60A+ (6.7 GHz) line.
