Abstract:
    To find out the astrophysical processes responsible for gamma-ray
    burst (GRB), it is crucial to discover and understand the relations
    between their observational properties. This work was performed in the
    GRB rest frames using a sample of 62 long Swift GRBs with known
    redshifts. Following the earlier analysis of the correlation between
    afterglow luminosity (L*a) and break time (T*a), we extend it to
    correlations between the afterglow and the prompt emission GRB
    physical parameters.

Note (1): One RGB name was corrected at CDS (GRB 061115 does not exist,
     this name was correctde into GRB 060115). The classes are:
   long = long GRBs with u<4
   IC   = intermediate GRB class (between long and short GRBs)
Note (2):  See Eq.(1) of the paper:
   L*a=4πD2(z)FX(T*a)/(1+z)(1-β)
   where D(z) is the source luminosity distance.
