% QARTS_SENSOR   Defines setting fields for ARTS sensor response calculations
%
%    The function provides default values for all recognised fields and a 
%    description of each field. Default value is normally NaN, but
%    exceptions exist when some standard choice exists. To list default
%    values just type 'arts_sensor'.
%
%    This function is organised in such way that *qcheck* and *qinfo*
%    can be used.
%
% FORMAT   [H,I] = arts_sensor
%        
% OUT   H  Setting structure with default values for all recognised fields.
%       I  Includes same fields as H, where the content of each field
%          is a description string (used by *qinfo*).
