Charge exchange spectroscopy diagnostic
Notation of array of structure indices: itime indicates a time index; i1, i2, i3, ... indicate other indices with their depth in the IDS. This notation clarifies the path of a given node, but should not be used to compare indices of different nodes (they may have different meanings).

By convention, only the upper error node should be filled in case of symmetrical error bars. The upper and lower errors are absolute and defined positive, and represent one standard deviation of the data. The effective values of the data (within one standard deviation) will be within the interval [data-data_error_lower, data+data_error_upper]. Thus whatever the sign of data, data_error_lower relates to the lower bound and data_error_upper to the upper bound of the error bar interval.Full path name | Description | Data Type | Coordinates | |||||||||||||||

aperture/geometry_type | Type of geometry used to describe the surface of the detector or aperture (1:'outline', 2:'circular', 3:'rectangle'). In case of 'outline', the surface is described by an outline of point in a local coordinate system defined by a centre and three unit vectors X1, X2, X3. Note that there is some flexibility here and the data provider should choose the most convenient coordinate system for the object, respecting the definitions of (X1,X2,X3) indicated below. In case of 'circular', the surface is a circle defined by its centre, radius, and normal vector oriented towards the plasma X3.
