_F_o_r_m_a_t:

     The two variables, 'steigerwald' and 'coulissenhieb' are lists,
     where the first component, 'coord', is a matrix of two columns
     giving the positions of the trees, and the second component gives
     the stem diameters. The third component, 'author', gives a short
     description of the data set.

_D_e_t_a_i_l_s:

     Both forests can be found in the the North of Bavaria, Germany;
