Wendland.awen and Wendland.bwen

Hello

I understand that awen comes from 7/4pi = 0.557 in the 2D case, but I cannot figure out where bwen comes from?

My understanding is that the "-" comes because of "odd^3" will always produce odd, and that the extra 1/h comes from gradient estimation. Could anyone kindly explain it in bit more detail / show me briefly the math to derive -2.7852?

Kind regards
