Values of saturation index greater than, equal to, and less than zero represent oversaturation, equilibrium, and undersaturation, respectively.
Values equivalent to zero represent UCIP processing, positive values indicate super-capacity, and negative values represent limited capacity.
Nugget values greater than zero represent a combination of experimental error and of unresolved spatial variability occurring at scales smaller than inter-sampling lag distance.
Materials where the value of η is closer to zero represent a fabrication and processing method that produces a more ideal material.
Similarly, the axis-2 coordinates on either side of zero represent the semiannual variations and their amplitudes showing high TEC values in a day, whereas the dots around the midpoint (zero) represent the reference values with low amplitude in the seminal variations.
The F1-score values are defined on the interval ((0,1)), and if they are near one they represent a better classification, while small values, near zero, represent a low classification quality.
