Integrated intensity maps of HCN, H13CN, and HC15N (from left to right) in Jy beam km s−1. The maps are centered at α = 11:01:51.81150, δ = −34:42:17.2636 (J2000.0). The visibilities were projected on the same spatial grid and convolved to a synthesized beam of HPBW 0.26″ × 0.21″. The emission is centered on the systemic velocity of 2.83 km s−1 and is integrated over 5 km s−1 for HCN and 2 km s−1 for the less abundant isotopologs.
