+function geteqdskJET(shot,time,nrg,nzg,savedir,deltaz,efitlab,uid,seqd,varargin);
+%
+% save eqdsk file to savedir/JET_EQDSK_shot_ttime
+%
+% examples:
+% geteqdsk(shot,time,33,65,'/tmp')
+%
+% INPUTS :
+% shot : shot number
+% time : single time slice of analysis
+% nrg, nzg: nb of R and Z points for R,Z grid
+% OPTIONAL
+% savedir: directory to save eqdsk file (default: './')
+% deltaz: shift equilibrium vertically
+% = 0: (default) no shift
+% = -99: shift so that zmag=0 (thus deltaz=-zmag)
+% otherwise: shift Z position by this amount
+% efitlab : 'efit' or 'eftm' (default: 'efit')
+% uid: user id if different from main database (default: 'jetppf')
+% seq: sequence number if not last one required (default: 0)
+%
+% varargin{1}: plot option: 0: do not plot contours, >0 plot contour with varargin{1} nb of contours (60 is good)
+%
+% OUTPUTS
