Logical

class jwst.transforms.Logical(condition, compareto, value, **kwargs)

Bases: astropy.modeling.core.Model

Substitute values in an array where the condition is evaluated to True.

Similar to numpy’s where function.

Parameters:

• condition (str) – A string representing the logical, one of GT, LT, NE, EQ
• compareto (float, ndarray) – A number to compare to using the condition If ndarray then the input array, compareto and value should have the same shape.
• value (float, ndarray) – Value to substitute where condition is True.
