-def get_angle(a, b, c):  # a,b,c where b is the vertex
-    """
-    Calculate the angle between two vectors where b is the vertex of the angle.
-
-    This function computes the angle between vectors `ba` and `bc`, where `b` is the vertex and `a` and `c` are the endpoints of the angle.
-
-    Parameters:
-    ----------
-    a : (n, 3) numpy.ndarray
-        Array of coordinates representing the first vector.
-    b : (n, 3) numpy.ndarray
-        Array of coordinates representing the vertex of the angle.
-    c : (n, 3) numpy.ndarray
-        Array of coordinates representing the second vector.
-
-    Returns:
-    -------
-    numpy.ndarray
-        Array of angles (in radians) between the vectors `ba` and `bc`.
-
-    Notes:
-    ------
-    - The function handles multiple vectors by using broadcasting.
-    - The angle is calculated using the dot product formula and the arccosine function.
-
-    Example:
-    --------
-    >>> a = np.array([[1, 0, 0]])
-    >>> b = np.array([[0, 0, 0]])
-    >>> c = np.array([[0, 1, 0]])
-    >>> get_angle(a, b, c)
-    array([1.57079633])
-    """
-    a = np.atleast_2d(a)
-    b = np.atleast_2d(b)
-    c = np.atleast_2d(c)
-    ba = np.subtract(a, b)
-    bc = np.subtract(c, b)
-    cosine_angle = np.sum(ba * bc, axis=-1) / (np.linalg.norm(ba, axis=-1) * np.linalg.norm(bc, axis=-1))
-    return np.arccos(cosine_angle)

     Calculate the fractional flux of sunlight reflected from the Moon to the satellite.
