The correlation between parameters in the stellar radial velocity fit. The numbers overlaid on each plot give the value of the covariance of the parameters. Each parameter is shown with the mean of its posterior distribution subtracted. These mean values are given at the end of the caption. The parameters shown are as follows: residual zero-point offset γ; time of inferior conjunction TC; log of the period ﹩\mathrm{log}P;﹩ log of the stellar radial velocity semi-amplitude ﹩\mathrm{log}({K}_{\star });﹩ log of the stellar surface gravity ﹩\mathrm{log}(g);﹩ effective temperature of the star ﹩{T}_{\mathrm{eff}};﹩ stellar metallicity [Fe/H]; time of superior conjunction TS; stellar mass M; stellar radius R; stellar luminosity L; stellar density ﹩{\rho }_{\star };﹩ orbital period P; semimajor axis a; the planet equilibrium temperature ﹩{T}_{\mathrm{eq}};﹩ the incident irradiation received by the planet Finc; the stellar radial velocity semi-amplitude K; the minimum mass of the planet ﹩{M}_{{\rm{P}}}\sin (i);﹩ the mass ratio ﹩{M}_{{\rm{P}}}/{M}_{\star };﹩ total duration of any potential transit of the planet T14; and the a priori transit probability ﹩{P}_{T,G}﹩. The mean values subtracted from the axis for each parameter in the plots are as follows: ﹩{\gamma }_{\mathrm{mean}}=0.032﹩ m s−1, ﹩{T}_{C,\mathrm{mean}}=2456326.9313661﹩ days, ﹩\mathrm{log}{P}_{\mathrm{mean}}=0.6264212﹩, ﹩\mathrm{log}({K}_{\star ,\mathrm{mean}})=1.740﹩, ﹩\mathrm{log}{(g)}_{\mathrm{mean}}=4.5﹩ cgs, ﹩{T}_{\mathrm{eff},\mathrm{mean}}=5786﹩ K, ﹩{[\mathrm{Fe}/{\rm{H}}]}_{\mathrm{mean}}=0.20﹩, ﹩{T}_{S,\mathrm{mean}}=2456329.047﹩ BJD, ﹩{M}_{\star ,\mathrm{mean}}=1.10﹩ M, ﹩{R}_{\star ,\mathrm{mean}}=1.02\,{R}_{\odot }﹩, ﹩{L}_{\star ,\mathrm{mean}}=1.08\,{L}_{\odot }﹩, ﹩{\rho }_{\star ,\mathrm{mean}}1.49=\mathrm{cgs}﹩, ﹩{P}_{\mathrm{mean}}=4.230787﹩ days, ﹩{a}_{\mathrm{mean}}=0.053\,\mathrm{au}﹩, ﹩{T}_{\mathrm{eq},\mathrm{mean}}=1227﹩ K, ﹩{F}_{{inc},\mathrm{mean}}=0.52\times {10}^{9}﹩ erg s−1, ﹩{K}_{\star ,\mathrm{mean}}=54.9﹩ m s−1, ﹩{M}_{{\rm{P}}}\sin {(i)}_{\mathrm{mean}}=0.47﹩ MJ, ﹩{M}_{{\rm{P}}}/{M}_{\star ,\mathrm{mean}}=0.00040﹩, ﹩{T}_{14,\mathrm{mean}}=0.12﹩ days, ﹩{P}_{T,G,\mathrm{mean}}=0.09﹩.
