Notes. (a)Velocity width of the detected line measured with a detection higher than 3σ. (b)Integrated intensity over the whole emission area, obtained from a 3σ contour over the moment 0 map. (c)Two c-C3H2 lines are blended: (60,6-51,5) and (61,6-50,5). Integrated intensity and peak intensity uncertainties consider a 10% absolute calibration uncertainty and the noise in the images.
