CN model images and radial intensity profiles (black and gray) from the DALI models, after convolving with a 0.″3 beam for both sources. Model M2 for Sz 71 has an increased UV luminosity relative to M1. The black dashed vertical lines indicate (approximately) the CO snow line locations in the models. The observed radial profiles of CN are shown in green, together with their 1σ errors.
