Left: distribution of kinetic temperature and velocity dispersion for all the coherent cores and the shell-1 and shell-2 regions. Shells-1 and shells-2 are defined as two consecutive shells of width equal to one beam around the respective coherent cores. Each kernel density distribution was normalised to have a peak density of 1. The contours show normalised KDE levels of 0.1, 0.25, 0.4, 0.55, 0.7 and 0.85. Right: same as the left panel, but without the regions L1688-SR3, L1688-SR2, and Oph-A, and ignoring one beam at each star position. This is done to remove the effect of external heating, and possiblecontribution from prostellar feedback.
