Description of neoclassical tearing modes
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).
Lifecycle status: alpha since version 3.0.4
Last change occured on version: 3.0.4
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 | |||||||||||||||

Often data are obtained by a chain of processes, however only the last process input are recorded here.
