Fig. 3: Stokes-I and V/I profiles of the Ellerman bomb at the ___location marked by the red cross in Figs. 1 and 2.
From: Magnetic diffusion in solar atmosphere produces measurable electric fields
The left column shows Stokes-I profiles normalized by the intensity at the continuum, \({I}_{{{{\rm{C}}}}}\), in the Ca II H (a), Hε (c), Fe I 630.15 nm and Fe I 630.25 nm (e), and Ca II 854 nm lines (g), and the right column shows Stokes-\(V/I\) profiles in the Ca II H (b), Hε (d), Fe I 630.15 nm and Fe I 630.25 nm (f), and Ca II 854 nm lines (h). Black crosses and bars are measured data points. Error bars are shown as the standard deviation in the continuum only for Stokes-V/I in the Ca II H and Hε, because they are too small to see in the other plots. Red lines show synthesized profiles from the best 50 fitting results of Departure coefficient aided Stokes Inversion based on Response functions (DeSIRe30) inversions, which were run 10,000 times while varying the initial atmospheric model (see, methods subsection Inversion with DeSIRe). A blue dashed curve in panel d shows an average profile of those pixels that have similar Stokes-V/I signals to the Ellerman bomb in weak photospheric lines, i.e., Fe I at 396.96 nm, Cr I at 396.97 nm, Fe I at 397.02 nm, and Ni I at 397.04 nm, from quiet regions around the Ellerman bomb. The narrow spectral lines in 630.20 and 630.28 nm are telluric lines of O2. Source data are provided as a Source Data file.
