bvtnorm_func

function to evaluate a bivariate normal momentum distribution

bvtnorm_func(p_perp, p_par, n, center, covariance, K)

Arguments

p_perp	numeric value of perpendicular momentum component
p_par	numeric value of parallel momentum component
n	numeric particle density.
center	numeric center of distribution (2d vector, c(p_perp, p_par))
covariance	numeric covariance of distribution (2 by 2 matrix)
K	numeric normalizations constant

Value

numeric value of momentum distribution at (p_perp, p_par)
