XMM-Newton and NuSTAR spectra of XMMU J173029.8–330920 fit with tbabs*pcfabs*(reflect*MCVSPEC + gauss). This fit utilised an initial mass of 1.2 M_⊙ and thus an R_m/R ratio of 26. The specific accretion rate for this fitting was 15 [g cm⁻² s⁻¹], resulting in the best-fit WD mass of $\sim 1.{28}_{-0.23}^{+0.12}{M}_{\odot }$, which is consistent with the initially assumed value of 1.2 M_⊙. The black, red, green, and blue data points are from EPIC-pn, MOS2, FPMA, and FPMB, respectively.
