Yost 2007 ROTSE-III暴本身阶段的光学观测

主要内容:
给出了一些暴本身做了光学观测的结果，很多没有看到，只给出了流量上限。不过上限也对模型的限制有作用的。也有一些看到了的数据。

We present several cases of optical observations during gamma-ray bursts (GRBs) which resulted in prompt limits but no detection of optical emission. These limits constrain the prompt optical flux densities and the optical brightness relative to the gamma-ray emission. The derived constraints fall within the range of properties observed in GRBs with prompt optical detections, though at the faint end of optical/gamma flux ratios. The presently accessible prompt optical limits do not require a different set of intrinsic or environmental GRB properties, relative to the events with prompt optical detections.
