Spectral and Spatial Variations of Flare Hard X-ray Footpoints

Authors: L. Fletcher & H. Hudson.


Colour Figures

The following are colour versions of the figures appearing in the article.

·   Figure 2
Pairwise correlation plots of broad-band flux ratios for the four flares studied, with the harder and softer bands set with boundaries at 10, 20, 30, 50 and 70 keV. The 'hysteresis' loops at the lowest energies (black crosses) show the presence of an uncorrelated slowly-varying component, identified with the hot flare plasma or the 'super-hot' component reported by Lin and Schwartz (1987). Yellow stars show the ratio of 30-20 to 50-30 keV fluxes. At the highest energies (blue diamonds) the correlation is almost the same for burst rise and fall.

·   Figure 3
Footpoint locations for each of the four flares derived from the CLEAN maps. These are colour-coded by time.

·  Figure 5 :
CLEAN source centroids (as opposed to CLEAN map centroids) during the 14 March 2002 flare, showing systematic motion along a ribbon.
