6 … Absorption of Sewell-Love-Scott (1985-II J. Phys. D.)
7 … Phi(pz) Absorption of Packwood-Brown 1982/XRS Alpha
8 … Phi(pz) Absorption of Bastin 1984/XRS Alpha
9 … Phi(pz) Absorption of Armstrong/Packwood-Brown 1981 MAS
10 … Phi(pz) Absorption of Bastin 1986/Scanning
11 … Phi(pz) Absorption of Riveros 1987/XRS
12 … Phi(pz) Absorption of Pouchou and Pichoir-Full (Original)
13 … Phi(pz) Absorption of Pouchou and Pichoir-Simplified (XPP)

The conventional ZAF correction is #1 which is also used in the FRAME program developed by Kurt Heinrich at NIST (NBS). The best results for silicates and other oxide samples are obtained with the Phi(Rho-Z) correction (#9) and with the original Love/Scott correction (#4) or the Full (Original) or Simplified (XPP) PAP correction. The default selection is #9.
