Fig. 1
Spectra of the newly detected 12.2 GHz methanol maser sources. Spectra of 6.7 GHz methanol masers (red) are also shown when taken on the same day, with exception of G183.348−0.575, where the interval between observations was 41 d. For comparison purposes, the scale of 6.7 GHz flux density was reduced by the factor given in the upper right corner.
