Multiband light curves from radio to X-rays (for the time interval
0.01-250 days after the burst onset) fitted with the multiple energy
injection model. Seven energy injection episodes (see Table 5),
indicated by vertical lines, can account for the observed behaviour.
The visible and NIR observations are corrected for extinction
