edges_cal.modelling.Foreground

class edges_cal.modelling.Foreground(*, parameters=None, n_terms=_Nothing.NOTHING, with_cmb=False, f_center=75.0, transform: ModelTransform = _Nothing.NOTHING)[source]

Base class for Foreground models.

Parameters:

f_center (float) – A “center” or “reference” frequency. Typically models will have their co-ordindates divided by this frequency before solving for the co-efficients.
with_cmb (bool) – Whether to add a simple CMB component to the foreground.

Methods

`__init__`(*[, parameters, n_terms, with_cmb, ...])	Method generated by attrs for class Foreground.
`at`(**kwargs)	Get an evaluated linear model.
`fit`(xdata, ydata[, weights])	Create a linear-regression fit object.
`from_str`(model, **kwargs)	Obtain a `Model` given a string name.
`get_basis_term`(indx, x)	Define the basis terms for the model.
`get_basis_term_transformed`(indx, x)	Get the basis term after coordinate transformation.
`get_basis_terms`(x)	Get a 2D array of all basis terms at `x`.
`with_nterms`([n_terms, parameters])	Return a new `Model` with given nterms and parameters.
`with_params`(parameters)	Get new model with different parameters.
