Enneal distillation curve, actual boiling point distillation curve, equilibrium vaporization curve – the conversion formulas among these three curves

En’s distillation curve, actual boiling point distillation curve, and equilibrium vaporization curve – what are the conversion formulas between these three curves? Which reference should I consult? Please help
I found a literature piece titled \"The Relationship between the Distillation Curves of 6 Major Crudes in China and Their Straight-Run Fractions\", and used the empirical formulas in it for calculations; I then compared these results with those obtained using the \"Petroleum Chemical Process Calculation Charts\". The errors turned out to be quite large. Could it be that I used the wrong empirical formula? Additionally, the oil property factor required by those charts is 11.8, which seems to indicate significant limitations. Or is it universal?
Try the method introduced in Petroleum Refining Engineering (4th Edition)
Petroleum Refining Design Data Chart Set (Volumes 1 and 2) – the data is of better quality
