Analysis of the ASASSN-V J091951.17-593306.9 system. In the right-hand side figures are the ETV variations plotted twice for pair B. The upper plot is the complete ETV diagram (i.e. apsidal motion + Römer delay + physical delay). The lower figure is plotted after subtraction of the apsidal motion. The blue curve is the final combined fit, the red one stands for the physical delay, and the magenta is the Römer delay (LITE).
