 By default, the model uses constant grid spacing along z-direction, but it can be stretched using the parameters [#dz_stretch_level dz_stretch_level] and [#dz_stretch_factor dz_stretch_factor]. In case of stretching, a maximum allowed grid spacing can be given by [#dz_max dz_max].\\\\
 Assuming a constant '''dz''', the scalar levels (zu) are calculated directly by:\\\\
-      zu(0) = - '''dz''' * 0.5 
+      zu(0) = - '''dz''' * 0.5\\\\ 
       zu(1) = '''dz''' * 0.5\\\\
 The w-levels lie half between them:\\\\
