Methanol MultiBeam Survey The Methanol MultiBeam Survey is a sensitive survey of massive young stars in the Milky Way Galaxy to detect methanol masers. The survey is carried out by scanning the telescope in galactic longitude. Spectra cover a 4-MHz band, corresponding to a velocity range of 180 km/s, with 2048 channels each separated by 0.09 km/s. Regions towards the galactic centre are scanned more than once with different velocity settings, so that all likely radial velocities are searched. A second frequency band centred on the 6035-MHz line of hydroxyl (OH) is observed in parallel with the methanol band.
