Fig. 14
Single-dish spectra of AS1. Red and black spectra show the single-dish optically thick MALT90 HCO+ J = 1−0 and optically thin MALT90 H13CO+ J = 1−0 transitions, respectively. The spatial and velocity resolutions are 38′′ and 0.11 km s−1, respectively. To improve the depiction, the spectra have been regridded to 0.45 km s−1. Green lines are fitted Gaussian and its center.
