LOS velocities at different times of the flare inferred from the inversions. From top to bottom: He I 10830 Å, Ca II 8542 Å at log τ=−3.5, and log τ=−2.0. The first column of velocity maps corresponds to the pre-flare phase (07:49–08:29 UT). The second column shows the peak of the flare (08:35–09:05 UT). The third and fourth columns depict the post-flare phases corresponding to the time ranges (09:07–09:36 UT) and (09:38–10:08 UT), respectively. We note that the top panels corresponding to the He I LOS velocities are clipped between ±10 km s⁻¹, whereas the middle and lower panels of Ca II LOS velocities are saturated between ±6 km s⁻¹. The black box shows the common FOV among all raster scans.
