Function: lfunparams
Section: l_functions
C-Name: lfunparams
Prototype: Gp
Help: lfunparams(ldata): returns the parameters [N, k, vga] of the L-function
  defined by ldata (see lfuncreate).
  The parameters Vga (gamma shifts) are returned to the current precision.
Doc: returns the parameters $[N, k, Vga]$ of the $L$-function
 defined by \kbd{ldata}, corresponding respectively to
 the conductor, the functional equation relating values at $s$ and $k-s$,
 and the gamma shifts of the $L$-function (see \kbd{lfuncreate}). The gamma
 shifts are returned to the current precision.
