Corner plot of various line parameters of the Sun for four temperature bins. From left to right, we show the central wavelength, line depth, convective blueshift, the correlation between LBL RV and mean RV, and the correlation between LBL RV and S index. The dashed lines and contours indicate the medians and the ±1σ kernel densities, respectively. The color-coding is the same as in Fig. 6.
