What we care about is the $S_{2(signal)}$. This is found simply by calculating $S_2$ from noise only, and subtracting it from $S_2$ overall.\\  The above image displays (from left to right) the $T_{max}$ map of the region of M51 that we're looking at (at speeds from   $______$ $-104 km/s$  to $______$ $-208 km/s$  % vmin*velocityres to vmax*velocityres ), a 2D map of $S_{2(signal)}$ where $\delta v=0$, and a 1D plot of azimuthally-averaged $S_{2(signal)}$ versus radius (for various values of $\delta v$).
