Coronal-property dependences on the effective loop length. Top: relation between the effective half loop length (see Eq. (63) for definition) and the time-averaged loop-top temperature (T_top, red circles) and coronal-base pressure (p_base, blue diamonds). Bottom: relation between the effective half loop length and the time-averaged loop-top electron density (n_e,top, red circles) and coronal-base electron density (n_e,base, blue diamonds). In both panels, lines represent the power-law fittings to the symbols.
