Observed spectra of the c-C₃H₂ transitions organised by core number. All of the transitions for the same core are plotted in the same subplot with vertical offsets for clarity. The Gaussian fit from pyspeckit are overplotted with a blue line. The spectra without a Gaussian fit indicate a non-detection. Core number labels with a colour background indicate c-C₃H₂ has been detected towards the source. Lastly, horizontal dashed grey lines indicate 3σ levels.
