pint.utils.find_prefix_bytime

pint.utils.find_prefix_bytime(model: TimingModel, prefixname: str, t: float | Time | Quantity) → int | ndarray[source]

Identify matching index(es) for a prefix parameter like DMX

Parameters:

model (pint.models.timing_model.TimingModel) –
prefixname (str) – Something like DMX or SWX (no trailing _)
t (astropy.time.Time or float or astropy.units.Quantity) – If not astropy.time.Time, then MJD is assumed

Returns:

Index or indices that match

Return type:

int or np.ndarray
