【 摘 要 】

To allow the online selection of events, the readout of the PANDA detector will reconstruct particles online. Several algorithms to perform this task in one of the subsystems, the electromagnetic calorimeter, are being developed. The algorithms are discussed, and a simple test case shows that they appear to behave similarly in terms of the ability to reconstruct events, and the time it takes to do this. However, some peculiarities, like the fact that the algorithms show the best performance in what is expected to be the worst-case scenario, still require additional investigation.
