Caption: Figure 1.

Left panel: a picture of the W51A region extracted from Ginsburg et al. (2017). Its background is made of millimeter emission of lines and continuum from ALMA observations: HC3N 24–23 in purple, C18O 2–1 in blue, CH3OH 42–31 in orange, 1.3 mm continuum in green. Right panel: the dots in blue, red, and green represent the overall distributions of the H2O, NH3(9,6), and CH3OH 42–41 masers in W51A, overlaid on the gray K-band continuum background detected in our VLA observation.
