AbstraktAbstract
The Gamma-Ray burst Optical Near-infrared Detector (GROND) offers early time data of Gamma Ray Burst (GRB) afterglows in 4 optical and 3 near-infrared (NIR) bands simultaneously. We extended the SCALEFIT package to allow for joint fits of GROND and Swift/XRT data. Using GRB 140512A, we demonstrate the improvements over fitting X-ray data only. We are able to constrain some of the parameters of the fireball model, for others we derive limits.
