This computes the background component at locations x and y.

The background component is defined as

\[Bx+Cy+D\]
Parameters:

  • x (ndarray) – The x values where the background is to be computed at

  • y (ndarray) – The y values where the background is to be computed at

Returns:

The background according to the model

Return type:

ndarray
