Nobeyama mapping survey of SCUBA-2 cores

We present the results of on-the-fly mapping observations of 44 fields containing 107 SCUBA-2 cores in the emission lines of molecules N_2_H^+^, HC_3_N, and CCS at 82-94GHz...我们报道了44个天区的随动测绘观测结果，这些天区包含107个SCUBA-2致密核，观测频段为82-94GHz，覆盖分子二氮合氢离子（N₂H⁺）、氰基乙炔（HC₃N）及碳硫化物自由基（CCS）的发射谱线。
