  4. Wald on HC3 (Internal Report 2018)
  5. Weighted_Kato on HC3 (Wandji Nyamsi et al. 2014, 2015, and 2019)
  6. Discretized_Kato on HC3 (Wandji Nyamsi et al. 2014, 2015, and 2019)
  7. Udo et Aro applied onto GHI from CAMS Radiation Service
  8. Szeicz on CAMS-Rad
  9. Jacovides on CAMS-Rad
  10. Wald on CAMS-Rad
  11. Weighted_Kato on CAMS-Rad
  12. Discretized_Kato on CAMS-Rad
