Notes. The spectral parameters are obtained from Gaussian fitting. aThe JVLA spectrum toward Cep A is extracted from the Effelsberg-beam-sized region (FWHM 49′′). b For G34.26+0.15, the JVLA beam samples the NH3 (9,6) spectrum over a region of radius 3′′.5, which contains all detected NH3 (9,6) emissions.
