erwans3.utils.gauss_sph(amp: Union[float, Quantity], center: ndarray, vec: ndarray, sig: Union[float, Quantity], bkg: Optional[Union[float, Quantity]] = None, norm: bool = False) → Union[float, Quantity]

Compute a 3D spherical Gaussian function.

Parameters:

• amp (float or Quantity) – Amplitude of the Gaussian.

• center (ndarray or SkyCoord or BaseRepresentation]) – Center of the Gaussian.

• vec (ndarray or SkyCoord or BaseRepresentation) – Vector for the Gaussian.

• sig (float or Quantity) – Standard deviation of the Gaussian in radiant.

• bkg (float or Quantity or None, optional) – Background value to add to the Gaussian. Default is None.

• norm (bool, optional) – If True, normalize the Gaussian. Default is False.

Returns:

Value of the spherical Gaussian function.

Return type:

float or Quantity
