description The UNBab(E)mapping function models should be simplified 10 allow fatter calculation and also better undemanding of the models.

There are 7 mathematical operations for tWSoi(£)'o he carried out before getting the mapping function scale factor. The mapping functions for tWfloft(£) models for hydrostatic and non hydrostatic components are given in a form of continued fraction arc to be simplified, due to its ability to calculate mapping function value down to 2 degree of elevation angle.
