Fig. 5
Doppler velocities obtained with SIR (top) based on the the Fe i λ1078.3 nm (left) and Si i λ1078.6 nm (right) lines, respectively. Line-fitting (bottom) yields LOS velocities of the chromospheric Ca iiλ854.2 nm (left) and photospheric Si i λ853.6 nm (right) lines. Note the different scale bar for the velocities from the Ca ii line.
