He gives representations of both a gravitational and a constant magnetic field as such analogues in order to solve now the spatial problems of the separation of field as well as analytic extension through the surface and into the domain with sources.
For CPs defined by <3 km point distance, density was quadrupled in Aberdeenshire when compared to <15 separation of field boundaries, and quintupled in Ayrshire (Table 5).
More important, certain experiments that require complex and expensive technical efforts at high fields can be easily realized at ultra-low fields, such as the simultaneous detection of several nuclei33, the separation of detection field and polarizing field, or the variation of the polarizing field.
Data from pairs of injections in the same animal revealed that the separation of area 18a projection fields for a given separation of injection sites was more variable in enucleated than in control rats.
As a consequence, separation of induced fields at periods longer than, say, a few months from rapid core field changes is not possible.
In this approach, all magnetic sources are co-estimated, resulting in optimal separation of the fields (Sabaka and Olsen, 2006).
But, for agencies as used to the traditional church-and-state separation of these fields as are editors, these are strange new times.
Due to varying green tones, the grass pixel ratio differs largely on various datasets; hence, it is not wise to set the threshold statically for the separation of far field and non-far field views.
We end this section by stressing that our way of looking at geomagnetic field and SV data, be they observed or main field model time series, is quite different from the current approach based on a separation of the field constituents according to various terms of the spherical harmonic expansion of the field.
Such models co-estimate the various source fields through a grand inversion and perform a mathematical separation of the field into its internal and external parts.
