Examples of the inversion results for different pixels in the field of view of set B. (a) Intensity at the core of the Ca II line. The colours of the marked pixels correspond to the examples displayed on the other panels. (b) Temperature stratification inversion results at the range log τ₅₀₀ = [ − 5, −6] for the different marked pixels on panel (a). Black line corresponds to the temperature stratification of the original input model. (c) Synthesised profiles as a result of the inversions (continuous lines) compared to the observed spectral profiles (dots) for the Mg II k line. (d) Same as panel (c) for the Mg II h line. (e) Same as (c) and (d) for the Ca II line.
