%
% INPUT:
% shot: shot number
% data_type: type of the required data. Ex.: 'Ip', 'zmag', 'rmag','sxr', 'ece', 'sxR'
% 'MPX'
% optional:
% varargin{1}: channel status 1= unread yet, 0= read
% 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 magnetic axis
%
% function needed: mds functions-xtomo_geometry-get_xtomo_data (Furno's routines)
% get_mdsdata (Reimerdes's routine)VsxrTCVradius
% list of data_type currently available:
% '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{4}!)
% 'MPX' = soft x-ray from wire chambers
