Fig. 2


Panels a)c) show the temperature at τc = 0.95, 0.05 and 0.01, clipped at (5500, 6700), (4600, 5300), and (4300, 5200) K resp., for inversions made assuming depth-independent magnetic field and LOS velocity, and in panels d)f) the corresponding temperatures obtained with 2 nodes for the velocity and 3 nodes for BLOS. Note the absence of inverse granulation in panel b). Panels g) and h) show the LOS velocity at τc = 0.95 and τc = 0.05 from the inversions corresponding to panels d)f), and in panel i the LOS velocity from the inversions assuming constant LOS velocity (panels a)c)). The LOS velocities have been clipped at (− 4.5, 4.5), (− 2.3, 2.3) and (− 2.3, 2.3) km s-1. The bottom row (panels j)l)) show the LOS magnetic field (with 3 nodes for BLOS) at τc = 0.95, 0.05 and 0.01, clipped at (− 1000, 1500) G. Note the increasing area coverage (expansion with height) of the network field at smaller optical depths. The FOV shown is 25 × 18″.
