fix_inputs
(modelinstance, values)[source]¶ This function creates a compound model with one or more of the input values of the input model assigned fixed values (scalar or array).
- Parameters
modelinstance : Model instance. This is the model that one or more of the
model input values will be fixed to some constant value.
values : A dictionary where the key identifies which input to fix
and its value is the value to fix it at. The key may either be the name of the input or a number reflecting its order in the inputs.
Examples
>>> from astropy.modeling.models import Gaussian2D >>> g = Gaussian2D(1, 2, 3, 4, 5) >>> gv = fix_inputs(g, {0: 2.5})
Results in a 1D function equivalent to Gaussian2D(1, 2, 3, 4, 5)(x=2.5, y)
