Comparison of the trailed spectrogram from LRIS for the Hα and Hβ emission of ZTF J2008+4449 (upper-left and lower-left plots, respectively, in blue) with our model for the optically thin (central plots) and optically thick (right plots) emission from a half ring with R_in = 20R_WD and R_out = 35R_WD.
