Sentence examples for mean epoch at from inspiring English sources
We present in Table 2 rms differences between the models, for two different epochs (the mean epoch at 2014.3 and the reference epoch at 2015.0) and for the full expansion (i.e., N max = 25) or that truncated to SH degree and order 13 (corresponding to the IGRF candidate model).
The geographic distribution of the differences between V-ASM and Z-ASM truncated models is presented in Figs. 3 and 4 at their mean epoch and at 2015.0, respectively.
We show that the differences between these models are small when they are compared at the mean epoch of measurements for n ≤ 13.
These differences are moderate at the mean epoch of measurements, but they increase when the model is extrapolated to 2015.0, as seen in Fig. 4. Above northern Europe, the two models differ by more than 10 nT, except for B Y. The difference is less important in the southern hemisphere.
The mean epoch by epoch agreement for sleep stages was 88% (range 81 96%), mean arousal re-scoring differed by 0.5 (range: −16 to 20), and mean PLM index re-scoring differed by 0.1 (range: −1.5 to 2.1).
The mean epoch of measurements is 2014.3.
To simplify the discussion, we further assume that each node has the same mean epoch length.
However, the following derivation can be extended for the case of different mean epoch lengths.
In a study of a large dataset the mean epoch by epoch agreement between scorers for all records was 73% (range 67-82%) [ 31].
The orbital integration shows that the secular variations in three orbital elements – the ascending node, the argument of perigee, and the mean anomaly at epoch – are larger than the systematic error as results of the relativistic perturbations.
In contrast, the within electrode, temporal analyses showed extremely high correlations for all non-seizure time points, relative to the first epoch at 30 min prior to seizure, and again was highly reproducible between patients (global mean ± 2 SD correlation coefficient from non-seizure epochs for all patients: 0.97 ± 0.004).
