The predicted accidental counts the jth detector pair of measurement i is calculated by the equation:

*T*: The_{i}**times**in nano-seconds of measurement i given as an input. Default is 1.*S*: For measurement i and detector pair j, S_{ijk}_{ijk}is the**singles**count on the kth dector in the pair. For example in the first detector pair 1-2, the S_{ij1}detector is the singles count on detector 1. Default of the singles count is 0.*W*: The coincidence_{k}**window**duration for the jth detector pair given as an input. Default is 0.

More details on the equation can be found in the Photonic State Tomography paper by Joe Altepeter. The accidental counts are calculated in the filter_data() function.
