  • FCUL_A.F - Function to compute the global total FCULa mapping function, dependent on latitude, height, and surface temperature. [1]
  • FCUL_B.F - Function to compute the global total FCULb mapping function, dependent on latitude, height and day of year. [1]
  • FCUL_ZD_HPA.F - Subroutine to compute the Mendes-Pavlis zenith total delay, for optical wavelengths, valid for infrared to ultraviolet.[1]
  • GMF.F - Subroutine to compute the Global Mapping Functions, GMF. [2]
  • VMF1.F - Subroutine to compute the Vienna Mapping Functions 1, VMF1, to be used with "a" coefficients computed for a given site.[2] (Updated March 26, 2012)
  • 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. [2] (Updated March 26, 2012)
  • GPT.F - Subroutine to compute the Global Pressure and Temperature, based on spherical harmonics up to degree and order 9. [2]
  • APG.F - Subroutine to compute the asymmetric delay d in meter caused by gradients. The north and east gradients are also provided, based on spherical harmonics up to degree and order 9.[2]
