Notes. Given are the name (including the maser frequency and spot label A.B, etc.), Right Ascension and Declination, peak flux density, rms and integrated flux density, peak velocity and minimum/maximum velocity of maser spot, and the positional uncertainties. Empty lines separate maser sites. Associations (ass.) ES: evolved star, D: double peaked, D?: potentially double peaked with 2nd component either two weak to be firmly identified or outside the imaged velocity range, BS, RS or wkS: in the GLIMPSE images a bright, red or weak star is seen co-spatial with the maser site, SF: star formation, SNR: supernova remnant, PN: planetary nebula, Star: star, nPL: near a pulsar, Sim: according to Simbad database, rc: cm continuum emission from Wang et al. (2018). The full table is available at CDS.
