tomtag.count_twofolds ============================================= .. raw:: html

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
