tomtag.sync_to_clock

tomtag.sync_to_clock(tagsA, tagsB, sizeA, sizeB, tcc)

[source]

given a signal that was registered with an untrusted clock, if you have access to a trusted periodic signal registered with the same untrusted clock, you can make the adjust the tags, given this knowledge about the periodic signal.

• Parameters
  • tags_signal: ndarray(dtype=int)
    • Timetags of the first channel.
  • tags_periodic: ndarray(dtype=int)
    • Timetags of the second channel.
  • size_signal: int
    • Number of timetags in the first channel.
  • size_periodic: int
    • Number of timetags in the second channel.
  • sync_period: int
    • The period of the periodic signal, in integer multiples of the timetag precision.
• Returns
  • coincidences: list
    • An array correspoding to the delays where each entry is the number of identified coincidences when the input tags where shifted by that specific delay.

Examples

>>> import tomtag as tt
>>> import numpy as np
>>> tagsA = np.array([12,679,1289,1487])
>>> tagsSync = np.array([20,409,879,1287])
>>> period = 400
>>>
>>> hist = tt.sync_to_clock(tagsA, tagsSync, len(tagsA), len(tagsSync), period)
