Fig. 2


X-ray light curve of r2-75. Simple exponential or linear models do not fit the data (χν are around 30 and 60 respectively). A better fit instead is a combined model consisting of an initially exponential decay followed by a longer, linear phase. These models are not only better fits, but are also consistent with the results of Shahbaz et al. (1998). The origin of the graph, in time, corresponds to first Swift observation.
