 """Creates a waveform generator for use with a model. Parameters variable_params : list of str The names of the parameters varied. data : dict Dictionary mapping detector names to either a :py:class:`<pycbc.types.TimeSeries TimeSeries>` or :py:class:`<pycbc.types.FrequencySeries FrequencySeries>`. recalibration : dict, optional Dictionary mapping detector names to :py:class:`<pycbc.calibration.Recalibrate>` instances for recalibrating data. gates : dict of tuples, optional Dictionary of detectors -> tuples of specifying gate times.
