The Circumnuclear Environment of IRAS 20551-4250: A Case Study of AGN/Starburst Connection for JWST

Table 1

Properties of the detected mid-IR emission lines. We measured the fluxes with the IDL package SMART by means of a Gaussian fitting. We use the most recent version of the IRS pipelines; thus our estimates are more reliable than those previously published.
