Measured values

Path to the source data for each measurement in the IMAS data dictionary, e.g. ece/channel(i)/t_e for the electron temperature on the i-th channel in the ECE IDS

Exact time slices used from the time array of the measurement source data. The time slice is indicated for each measurement point considered in the fit since measurements may come from different and thus asynchronous diagnostics. If the time slice does not exist in the time array of the source data, it means linear interpolation has been used

In case the measurements are averaged over a time interval, this node is the full width of this time interval (empty otherwise). In case the slicing/averaging method doesn’t use a hard time interval cutoff, this width is the characteristic time span of the slicing/averaging method. By convention, the time interval starts at time_measurement-time_width and ends at time_measurement.

Integer flag : 1 means local measurement, 0 means line-integrated measurement

Normalized toroidal flux coordinate of each measurement (local value for a local measurement, minimum value reached by the line of sight for a line measurement)

Normalized poloidal flux coordinate of each measurement (local value for a local measurement, minimum value reached by the line of sight for a line measurement)

Weight given to each measured value

Standard deviation of the measurement error

Value reconstructed from the fit

Squared error normalized by the weighted standard deviation considered in the minimization process : chi_squared = weight^2 *(reconstructed - measured)^2 / sigma^2, where sigma is the standard deviation of the measurement error
