Parameter maps for each ortho line. Left to right: flux with velocity and width imposed to be those of S(1) line. Line flux, velocity, and width with free parameters. Top to bottom: 1−0 S(1), S(3), Q(1), and Q(3) lines plus the 1−0 S(0) line maps obtained with the multiline fit. Maps are centered on Srg A*. The color bars are the same for all lines and as in Fig. 2. Symbols as in Fig. 2.
