Six upper panels (loops A - F): Evolution of correlation coefficients of propagating
disturbances observed simultaneously in 171 Å and 195 Å bandpasses with the distance along six
different slits. The solid lines show the correlation of unfiltered data while the dashed lines show the
correlation of the signals after subtraction of slower variation. The dotted lines are the best-fitted
straight lines. Two lower panels: Evolution of correlation coefficients of simulated signals. The left
panel shows the correlation for the same angle with the line of sight, but for different temperatures
, , and and , , and for the solid, dotted
and the dashed line, respectively. The right panel shows varying angle and ,
, and for the solid, dotted and dashed lines, respectively, while keeping the temperature
the same. The dash-dotted lines in both panels are the correlation of the simulated signals with
amplitude noise added (from King et al., 2003). |
