The errors provided are:
sigma^2(q/p) : charge (plus or minus one) divided by magnitude of momentum
sigma^2(dxdz) : direction tangent in local xz-plane
sigma^2(dydz) : direction tangent in local yz-plane
sigma^2(x) : local x-coordinate
sigma^2(y) : local y-coordinate
plus the relevant correlation terms.

Constructing class from standard deviations of the individual parameters, making the covariance matrix diagonal.
The sequence of the input parameters is sigma(x), sigma(y), sigma(dxdz), sigma(dydz), sigma(q/p), but the resulting covariance matrix has the same structure as the one described above.
