Notes. Luminosities include a multiplicative factor of two to make them comparable with PAHFIT-derived measurements (Smith et al. 2007), and they are extinction-corrected. The last row corresponds to the measurements from the Spitzer/IRS spectrum of J1509 reported by Zakamska et al. (2016), with the luminosities multiplied by two. Upper limits at 3σ are indicated with the “<” symbol for non-detections. The SFRs listed in column 6 are calculated from L11.3 μm following Eq. (12) in Shipley et al. (2016), which uses a Kroupa initial mass function. Columns 7 and 8 correspond to the 11.3/6.2 μm PAH and 6.2 μm PAH/H20-S(1) flux ratios, and they do not include the multiplicative factor of two. Column 9 is the gas column density measured from the ALMA CO(2–1) observations studied in Ramos Almeida et al. (2022) using a radius of 0.4″ from the continuum peak to measure the flux, Eq. (1) in Bolatto et al. (2013), and assuming R21 = 1 and XCO = 2 × 1020 cm−2.
