372 unique targets were selected from the following methanol maser surveys: the Methanol Multi-Beam catalog (MMB; Caswell & Breen 2010MNRAS.407.2599C; Green+ 2010-2012, VIII/96), the Arecibo Methanol Maser Galactic Plane Survey (AMGPS; Pandian+ 2011ApJ...730...55P), the Torun catalog of 6.7GHz methanol masers (Szymczak+ 2012, J/AN/333/634), and other individual observations of known 6.7GHz methanol masers or MSFRs (Caswell+ 1995MNRAS.272...96C; Walsh+ 1997, J/MNRAS/291/261; 1998, J/MNRAS/301/640; Xu+ 2008A&A...485..729X; Caswell 2009, J/other/PASA/26.454). The observations were conducted with the VLA in C-configuration using five sessions from 2012 February 28 to April 16. Spectral line data used 2048 channels across 8MHz, yielding a channel spacing of 3.90625kHz at the central frequency of 6.6685192GHz and a velocity resolution of 0.176km/s. The continuum observations employed two 1GHz sub-bands from 4.9840 to 6.0080GHz (the low band) and from 6.6245 to 7.6485GHz (the high band) and each sub-band was divided into 16 channels.
