How to derive Equation 6 in this paper? #10

@HanshuYAN Thanks for your open-source code.

  1. Could you tell me how to derive Equation 6 in this paper?

  2. In the following code snippet, why is lambda_t and eta_t equal to the right equation? lambda_t = ( lambda_s * (t_e - t_s) ) / ( lambda_s *(t_c - t_s) + (t_e - t_c) ) eta_t = ( eta_s * (t_e - t_c) ) / ( lambda_s *(t_c - t_s) + (t_e - t_c) )
