Caption: Fig. 2.

Folded light curve of LMC X‐4, in the 0.1–2.4 keV energy range of ROSAT, corrected for the orbital motion with the orbital period fixed to 1﹩\fd﹩40839 (Levine et al. 1991). Our best‐fitting parameters are P₀ = 13.502930 ± 0.000029 s, a_X sin i = 26.62 ± 0.38 lt‐sec, and the mid‐eclipse time is JD 2,448,559.3588 ± 0.0022 (the errors are 1 σ).
