comp_dirty

erwans3.Visibility_Computor_class.comp_dirty(baseline: Quantity, vis: Quantity, freq: Quantity, mapout: Union[PixList, SHCoeff], phased_dir: Optional[Union[ndarray, CartesianRepresentation, SkyCoord]] = None)

Generate a dirty image based on a visibility set.

Parameters:

  • b (Quantity [m]) – Baseline vectors.

  • vis (Quantity [Jy]) – Visibility data.

  • freq (:class:`~astropy.units.Quantity`[Hz]) – Frequency of the visibility data.

  • mapout (SHCoeff or PixList) – Output map type (SHCoeff for spherical harmonic coefficients or PixList for pixel list).

  • phased_dir (SkyCoord, optional) – Phased direction for the visibility data (default is None).

Returns:

Dirty image map based on the visibility data.

Return type:

SHCoeff or PixList

Raises:

TypeError – If the mapout type is not supported.
