862 nm DIB EW and LOS-integrated extinction. Top: DIB EW from the Gaia DR3 catalogue as a function of the extinction Av integrated from the Sun to the target star. A power law is fitted to the data from Av=0 to Av=1.5 mag. Isocontours of target number densities have been drawn to illustrate the various contributions. Bottom: same as top, but for the second catalogue of averaged EWs in spatial bins.
