The text was completely rewritten, thanks mainly to J. Boehm, G. Hulley, A. Niell, and E. Pavlis In addition, a new set of subroutines is available: * FCUL_a.f - Function to compute the global total FCULa mapping function for SLR analyses, dependent on latitude, height, and surface temperature. Provided by V. Mendes. * FCUL_b.f - Function to compute the global total FCULb mapping function for SLR analyses, dependent on latitude, height and day of year. Provided by V. Mendes. * fcul_ztd_hPa.f - Subroutine to compute the Mendes-Pavlis zenith total delay, for optical wavelengths, valid for infrared to ultraviolet. Provided by V. Mendes. * gmf.f - Subroutine to compute the Global Mapping Functions, GMF, for radio techniques. Provided by J. Boehm. * vmf1.f - Subroutine to compute the Vienna Mapping Functions 1, VMF1, to be used with ”a” coefficients computed for a given site. Provided by J. Boehm. * vmf1_ht.f - Subroutine to compute the Vienna Mapping Functions 1, VMF1, with height corrections, to be used with ”a” coefficients computed for a grid. Provided by J. Boehm. * gpt.f - Subroutine to compute the Global Pressure and Temperature, based on Spherical Harmonics up to degree and order 9. Provided by J. Boehm.
