tomtag.count_twofolds

tomtag.count_twofolds(tagsA, tagsB, sizeA, sizeB, tcc)
Count the number of entries of two arrays that fall within the coincidence window of eachother.
  • Parameters
    • tagsA: ndarray(dtype=int)
      • timetags of the first channel.
    • tagsB: ndarray(dtype=int)
      • timetags of the second channel.
    • sizeA: int
      • number of timetags in the first channel.
    • sizeB: int
      • number of timetags in the second channel.
    • tcc: int
      • size of coincidence window, as multiple of tag precision.
  • Returns
    • count (int): The number of tags that fall within the coincidence window of eachother between tagsA and tagsB.

Examples

>>> import tomtag as tt
>>> import numpy as np
>>> tagsA = np.array([12,679,1289,1487])
>>> tagsB = np.array([20,409,1279,1887])
>>> tcc = 15
>>>
>>> counts = tt.count_twofolds(tagsA, tagsB, len(tagsA), len(tagsB), tcc)
>>> assert counts==2
