Abstract
We have made a comparison of the X-ray light curve of a sample of GRB afterglows with a known redshift. We have applied to this sample corrections factor in order to take into account cosmological effects on the light curves of the \ bursts. We observe a clustering of data around two groups in the flux vs time diagram of this sample. We study the properties of these two groups and discuss this result, in the light of the GRB fireball model.
