Averaged stratification of T and υ_LOS as a function of optical depth obtained from the inversions of the Ca II 8542 Å line. Upper-left and lower-left panels: stratification of T and υ_LOS in the umbra, respectively. The red and blue curves represent the umbral flash and quiescent umbra atmosphere, respectively. Panels on the right: stratification of the same physical parameters in the penumbra. The shaded areas in all panels demonstrate the distribution of the parameters normalized at each log τ position.
