Velocity measurements from this work (K17) compared to M16. The dotted lines show where the two measurements would be equal. Star 46, the binary, is indicated by a red circle. The K17 value of the velocity for the star is the mean of our four measurements. Star 26 is not shown because M16 measured ﹩{v}_{\mathrm{helio}}=-84.1\pm 8.2﹩ km s⁻¹, whereas we measured ﹩{v}_{\mathrm{helio}}\,=-375.6\pm 11.2﹩ km s⁻¹.
