Methods Documentation
- __call__(lon, lat, energy=None)#
Call evaluate method
- copy(**kwargs)#
- freeze()#

SpatialModel
Spatial model
- model
- plot(ax=None, geom=None, **kwargs)#
Plot spatial model.
- plot_error(ax=None, **kwargs)#
Plot position error
- plot_grid(geom=None, **kwargs)#
Plot spatial model energy slices in a grid.
- plot_interative(ax=None, geom=None, **kwargs)#
Plot spatial model.
- reassign(datasets_names, new_datasets_names)#
Reassign a model from one dataset to another
- Parameters
- datasets_namesstr or list
Name of the datasets where the model is currently defined
- new_datasets_namesstr or list
Name of the datasets where the model should be defined instead. If multiple names are given the two list must have the save length, as the reassignment is element-wise.
- Returns
- model
Model
Reassigned model.
- model
- to_region(**kwargs)[source]#
Model outline (
RectangleSkyRegion
).
- unfreeze()#
Restore parameters frozen status to default
