Comparison of NaI D lines with DIB-5780 for EW (top) and VEL (bottom). The median linear fit is shown in red while in pink are various realisations of the MCMC. The correlation is ρ = 0.30 for the EW and ρ = −0.01 for the VEL, while the median slope is ${0.127}_{- 0.016}^{+ 0.015}$ $0.127^{+0.015}_{-0.016}$ 8.4σ above zero, for EW, and $- {0.914}_{- 1.87}^{+ 1.96}$ $-0.914^{+1.96}_{-1.87}$ for VEL, fully consistent with zero.
