Corner plot of the fit transit model based on the single transit of K2-141 c in K2 C19 to update the ephemeris of the planet. Gaussian Priors were used on P, a/R_*. and cos i based on the values reported in Malavolta et al. (2018) who only used the observations in C12. We used the resulting transit time t₀ to recalculate the orbital period P. The transit time in this plot is expressed as BJD_TDB - 2458371.0 d.
