Add documentation to ExcessMapEstimator regarding the correlate_off parameter
@@ -59,6 +59,10 @@ class ExcessMapEstimator(Estimator):
If a model is set on the dataset the excess map estimator will compute the excess taking into account
the predicted counts of the model.
+ Some background estimation techniques like ring background or adaptive ring background will provide already
+ correlated data for OFF. In the case of already correlated OFF data, the OFF data should not be correlated again,
+ and so the option correlate_off should set to False (default).

Parameters

correlation_radius : ~astropy.coordinate.Angle
