Notes. Columns are (from left to right) designations of the targeted RSGs (names are taken from SIMBAD), right ascension, declination, peak flux density, rms noise, LSR velocity of peak flux density, LSR velocity range covered by maser emission (from a Gaussian fit), velocity-integrated flux density, and a reference number.
