95 GHz methanol integrated intensity vs. SiO (2−1) integrated intensity. The orange and purple dots represent the clumps hosting masers and maser candidates, respectively. The orange and purple circle are the sources with a single component. The orange and purple dashed lines depict the least-squares fitting results for methanol masers and maser candidates with a single component, respectively. The orange solid line represents the least-squares fitting results for methanol masers, as in Fig. 6b.
