Critical analysis of solar hard X-ray observations

The impulsive phase of a solar flare hard X-rays emission is a rich source of information to understand the physics processes acting during the flare phenomenon. Particularly, in some cases, it shows the superposition of many intensity variations with time scales of tens to tenths of seconds. Lookin...

Sumario:The impulsive phase of a solar flare hard X-rays emission is a rich source of information to understand the physics processes acting during the flare phenomenon. Particularly, in some cases, it shows the superposition of many intensity variations with time scales of tens to tenths of seconds. Looking for an objective method to separate and characterize these possible time scale fluctuations we tried the novel method of the Discrete Wavelet Transform (DWT), applying it to some hard X-rays flares observed with good time resolution (64 ms) by the Large Area Detector (LAD) of BATSE, an instrument on board the CGRO satellite.
