Our R-band light curves, combined with other published data, can be described by the smooth broken power-law function, with {alpha}_1_=-0.84+/-0.02 to {alpha}_2_=-0.48+/-0.03, 0.04 days after the gamma-ray burst. The optical light curves are characterized by shallow decays as was also observed in the X-rays which may have a similar origin, related to energy injection. However, our observations indicate that there is still a puzzle concerning the chromatic breaks in the R-band light curve (at 0.04 days) and the X-ray light curve (at 0.004 days) that remains to be solved.2007ApJ...654L..25Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/654/L25CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/641/L13 : Light-curve data for GRB 030329 (Gorosabel+, 2006)J/ApJ/642/L99 : R-band photometry of GRB 060206 (Wozniak+, 2006)J/ApJ/654/L21 : R-band light curves of GRB 060206 & GRB 060210 (Stanek+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/654/L25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/654/L25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/654/L25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/654/L25https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/654/L25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/654/L25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapGamma-rayOpticalInfrareddefaultJ/ApJ/654/L25/table1GRB 050319 Optical Afterglow PhotometryrecnoRecord number assigned by the VizieR team.
