VizieR Online Data Catalog: N in Galactic high-mass star-forming cores (Colzi+, 2018)

The 67 sources analysed in this work were observed with the IRAM-30-m telescope in 2014 August. We have used the FTS spectrometer (Fast Fourier Transform Spectrometer) to cover the frequency range 85.7-93.5GHz with a frequency resolution of 200kHz, corresponding to 0.6km/s at the observed frequencies.

We have observed the rotational transitions J=1-0 of HN¹³C, H¹⁵NC, H¹³CN and HC¹⁵N towards 67 massive star-forming cores to derive the ¹⁴N/¹⁵N ratios.
