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.
