Top: comparison of the optical-NIR spectrum of SN 2016dsg to the low-mass double detonation model from Boyle et al. (2017). The green band marks the strongest telluric absorptions. Bottom: the SDEC plot produced by TARDIS. Different colors are used to illustrate the contributions from different elements. Absorption is represented by negative values. “Interaction” in this context refers to radiation-matter interaction above the blackbody photosphere; “no interaction” means that photons escape freely.
