Fig. 15


Maximum formation heights, max z(τν = 1), of the Ca II K (blue), Ca II H (white), infrared Ca II triplet 8542 Å (black solid), and Mg II h (gray) lines in Model 2, sliced vertically along the main diagonal, where max z(τν = 1) is taken over all wavelength positions of the respective spectral line profile. The zero point is defined as the average height where the optical depth at 5000 Å is unity. Upper panel: gas temperature is indicated. Middle panel: mass density is shown. Lower panel: magnetic field strength is shown. The plasma β parameter is less than unity above and bigger than unity below the dotted line.
