Fit to the quenched ridge along the red line and the star-forming ridge along the blue line. The diamonds are the locations the Gaussian fits have indicated. The fits for the star-forming ridge line up very well whereas the fits for the quenched sequence only line up for a small section and have considerable scatter. This is mainly since most of the ridge has been removed due to completeness concerns so we are only measuring at the very high mass end of the ridge where it is likely to be more noisy.
