Inverse ammonia NH3(1, 1) spectra (i.e., −1 × TMB, where TMB is the originally measured main beam brightness temperature) toward the second serendipitously detected molecular core SS2C to show its signals, as obtained from off-positions, in emission. The “absorption” feature seen in the blue wing of the central NH3 line at offsets (0′′,0′′), (− 40′′,0′′), and (40′′,0′′) is the Doppler shifted ammonia emission line detected at offsets (320′′,440′′), (280′′,440′′), and (360′′,440′′) toward the source SS2B. The channel spacing is 0.039 km s-1; the spectral resolution FWHP = 0.045 km s-1. The red curves show the fit of a one-component Gaussian model to the original data.
