Scientific paper

The hardness-intensity correlation (HIC) during the decay phase of gamma-ray burst pulses can often be described by a simple power law. The pulse decays in multi-pulse bursts present power-law indices that are equal to within the errors. We find that in some pulses the HIC changes to a parallel power law, a feature that we graphically call a track jump. The use of the index constancy is proposed as an auxiliary tool for pulse identification, and examples of its application are given. .
