Inter-visibility of Triangulation stations

There is formula given by G.T. McCaw
where, h1= elevation of station !
            h2 = elevation of station B
             h= elevation between intervening station C
             2S = distance between stations A and B
           s+d = distance of C from A
          s-d = distance of C from B
        z = zenith distance from A and B
