propagate_add
(other_nddata, result_data)[source] [edit on github]¶ Propagate uncertainties for addition.
Parameters: other_nddata : NDData instance
The data for the second other_nddata in a + b
result_data :
ndarray
instanceThe data array that is the result of the addition
Returns: result_uncertainty : NDUncertainty instance
The resulting uncertainty
Raises: IncompatibleUncertaintiesException
Raised if the method does not know how to propagate the uncertainties.
-
