Sentence examples for main field coefficients from inspiring English sources

The field was computed using Eq. (2), starting with the main field coefficients for 2009.5 from CHAOS-2.

The relation is through the Gaunt/Elsasser matrix (H) whose elements depend on the main field coefficients which change with time (Whaler, 1986).

Since the parent model was computed for the epoch 2014.3, we advanced the main field coefficients to 2015.0 using the linear secular variation.

This suggests that our parameterization misses some magnetic field contributions, which in turn could introduce biases in the main field coefficients.

The coefficients of the average SV (given in Table 1) were calculated by dividing the difference between the main field coefficients predicted at 2010 and those forecast at 2015 by five years.

This generates a set of predicted secular variation and secular acceleration coefficients, which are added back to the main field coefficients to give the prediction of the main field for the following month.

The flow velocity and acceleration coefficients are related to the magnetic field via a set of equations which involve integrals of triple products of spherical harmonics and their spatial derivatives and the main field coefficient (Whaler 1986).

A model vector with the only non-zero main-field coefficient being is used as the starting point of the initial L2-norm fit.

The SV coefficients derived from a flow model are used to advect the main field Gauss coefficients forwards in time.

The main field, SV and flow coefficients are truncated at degree and order nmax = 14, and thus we have assumed that only large scale flows are responsible for the large scale SV.

Each month, a new set of matrices relating flow velocity and acceleration to secular variation and secular acceleration are computed based on the main field and secular variation coefficients.
