Notes. Columns 3 to 7 give the time interval,
, the pre- and post-jet break decay
slopes, α1, α2, and the
observed jet break time, tb,jet. The optical and X-ray
light curves were independently fitted for every GRB (Sect. 2.2). Owing this, two break times are given for GRB 060614.
Within the errors the break was achromatic, making it a good candidate for a jet
break. For the other GRBs we state the upper or lower limits on the jet break time
with respect to the identification of the dynamical regime shown in Table B.3. The overlapping time interval of the
late-time optical and X-ray afterglow is shown in the last two columns. † The
optical afterglow light curve of GRB 080721 shows an additional shallow break at
(129 ± 84) ks. The difference in the pre- and post-break decay slope is ≈ 0.25 in
agreement with Kann et al. (2010), which is
typical for a cooling break. This break is not a jet break.
