BestLime provides methods for computing the integral of a function f(z) times J(nu, z q), where J(nu, x) is a Bessel function of the first kind.New in version 1.2: (i) Add functions to compute integration weights for a given value of q. (ii) Use these weights to speed up integration calls that take several functions as argument. [...]

BestLime provides methods for computing the integral of a function f(z) times J(nu, z q), where J(nu, x) is a Bessel function of the first kind. The values of the function f(z) are required on an interpolation grid that is independent of q and can be selected by the user. [...]

**Nature of the problem:**The aim is to develop a code that allows for the evaluation of the evolution equations for the twist-3 parton distributions at LO in the strong coupling with a variable number of flavors. Standard techniques that have been developed for the twist-2 case cannot be straightforwardly applied because of the increased dimensionality of the problem. [...]

The continuous spectrum required by the Q-EXAFS monochromator can be realized by a Wiggler, Bending Magnet, or tapered Undulator. For the AppAnaXAFS beamline, the application of a 3-pole Wiggler is desired, if it can provide a flux of 10^12 photons on the sample [...]
