From: Astrometrically registered maps of H2O and SiO masers toward VX Sagittarii

Astrometrically registered velocity-integrated intensity maps of 22.2 GHz H2O and 43.1/42.8/86.2/129.3 GHz SiO masers obtained from the SFPR technique toward VX Sgr (in press manuscript14). The rms noise levels on the maps are 115.4, 18.01, 15.45, 33.69, and 11.59 Jy beam−1 m s−1, respectively, in order of the maser transition. The peak flux values are 573.62, 55.65, 38.08, 61.70, and 1.85 Jy beam−1 km s–1. The contour levels are adopted at 10 12 15 20 25 30 50... for multiples of each rms value
