ISCWSA Error Model Calculations

04 July 2017 Hi everybody,
I am looking for any example of ISCWSA Error Model calculations. I have input data: N,E, TVD calculated from azimuth inc and md. Now I want to calculate dimensions of elipse using ISCWSA error model. How to calculate error and sum it up  in station and between stations? I have read Introduciton to well positioning but I dont understand some equations(for example what is dr/dp in pg 172 appendix A, do I need it if I have calculated N,E, TVD by my function?).

I am writing master thesis about anticollision and I would be really appreciated if you could help.   .
Regards
