Format of distortion parameters (D1, D2)

I'd like to know the format of five distortion-parameters (D1 and D2) downloaded from the web interface.

I know the distortion-parameters of OpenCV is the following.
distCoeffs1: Input/output vector of distortion coefficients (k1,k2,p1,p2[,k3[,k4,k5,k6[,s1,s2,s3,s4[,τx,τy]]]]) of 4, 5, 8, 12 or 14 elements. The output vector length depends on the flags.
(Please refer to

Which D1 and D2 parameters correspond to which of the OpenCV's?

Our distortion coefficients exactly match the coefficients from OpenCV. Hence the order is:
k1, k2, p1, p2, k3
