Comparison of different tracers in Serpens South. Integrated-intensity maps (on a color scale) of (a) H13CN (1−0), (b) HN13C (1−0), (c) H13CO+ (1−0), and (d) N2H+ (1−0). The blue contours represent the respective integrated intensities. They vary from 10% to 90% of the peak integrated intensities in steps of 10%, where the peak integrated intensities are 1.57 K km s−1, 2.25 K km s−1, 4.26 K km s−1, and 30.24 K km s−1 for H13CN (1−0), HN13C (1−0), H13CO+ (1−0), and N2H+ (1−0), respectively. The black contours of HCNH+ (2−1) integrated intensities are the same as in Fig. 2a. The intensity was integrated over 7−9.5 km s−1 for H13CN (1−0), HN13C (1−0), and H13CO+ (1−0), while a broader range (5−9.5 km s−1) was chosen to cover the three main HFS components of N2H+ (1−0). The beam size is shown in the lower-right corner of each panel. In all panels, the (0, 0) offset corresponds to αJ2000=18h30m04s.19, δJ2000=−02°03′05″.5. The markers are the same as in Fig. 2.
