                       Distance4Tuple

4-Tuple `(distance2, delta_lat, delta_lon, unroll_lon2)` with the distance in `degrees squared`, the latitudinal `delta_lat = lat2 - lat1`, the wrapped, unrolled and adjusted longitudinal `delta_lon = lon2 - lon1` and `unroll_lon2`, the unrolled or original `lon2`.

Note: Use Function pygeodesy.degrees2m to convert `degrees squared` to `meter` as degrees2m(sqrt(distance2), ...) or degrees2m(hypot(delta_lat, delta_lon), ...).

Class Variable Details

  ### _Names_ Tuple specifying the `name` of each `Named-Tuple` item. Note: Specify at least 2 item names. Value:
      ('distance2', 'delta_lat', 'delta_lon', 'unroll_lon2')

  ### _Units_ Tuple defining the `units` of the value of each `Named-Tuple` item. Note: The `len(_Units_)` must match `len(_Names_)`. Value:
      (<class 'pygeodesy.units.Degrees2'>,
       <class 'pygeodesy.units.Degrees'>,
       <class 'pygeodesy.units.Degrees'>,
       <class 'pygeodesy.units.Degrees'>)
