function [trace,error,varargout]=loadJETdata(shot,data_type,varargin)
%
+% data_type:
+% 'Ip' = current
+% 'zmag' = vertical position of the center of the plasma (magnetic axis)
+% 'rmag' = radial position of the center of the plasma
+% 'ece' = electron cyclotron emission
+% 'sxr' = soft x-ray emission
+% 'sxR' = soft x-ray emission with varargout{1} option (requires varargin{5}!)
+%
+% Special case compatible with old gdat.m allows (JET related):
+% gdat(51994,'ppf','efit/xip',...)
%
% INPUT:
% shot: shot number
-% data_type: type of the required data. Ex.: 'Ip', 'zmag', 'rmag','sxr', 'ece', 'sxR'
-% optional:
-% varargin{1}: [i1 i2] : if not empty, assumes need many chords from i1 to i2
-% varargin{2}: channel staus 1= unread yet, 0= read
-% varargin{3}: zmag for varargout{1} computation
+% data_type: type of the required data.
+%
+% Meaning of varargin depends on data_type:
+%
+% data_type=sxr or ece:
+% varargin{1}: channel status: 1=unread yet, 0=read
+% (for traces with many channel, enables to load additional channels,
+% like SXR, ECE, etc.)
+% varargin{2}: [i1 i2] : if not empty, assumes need many chords from i1 to i2
+% varargin{3}: zmag for varargout{1} computation
%
% OUTPUT:
% trace.data: data structure
% trace.t: time of reference
% trace.x: space of reference
-% varargout{1}: intersection of the view lines with magnetics axis
+% error: error in loading signal (0=> OK, 1=> error)
+%
+% Additional Output arguments depending on data_type
+%
+% data_type=sxR:
+% varargout{1}: intersection of the view lines with magnetic axis
+%
+% functions needed: jetreaddata or mdsplus routines
%
-% function needed: mds functions-xtomo_geometry-get_xtomo (Furno's routines)
-% VsxrTCVradius-jetreaddata
-% list of data_type currently available:
-% 'Ip' = current
