Entire e-MERLIN map of 22 GHz maser emission from NGC 7538, including IRS1-3, IRS9, and IRS11, of the 22 GHz water maser line. Colored circles show the relative position of individual maser features, with color denoting the maser V_LSR, according to the color-velocity conversion code reported on the right side of the panel. The water maser positions reported by Galván-Madrid et al. (2010), corrected for proper motion (Moscadelli & Goddi 2014), are shown as crosses (same color-velocity conversion code) for comparison. The beam of the SOFIA observation is overlaid in black for comparison.
