The phrase "a core field" is correct and usable in written English.
It can be used to refer to a fundamental or essential area of study, research, or practice within a broader context.
Example: "Biology is considered a core field in the life sciences, providing essential knowledge for understanding living organisms."
Alternatives: "a fundamental area" or "a key discipline".
Note that this is not a core field and therefore telephone interviewers are not obliged to ask for this information.
Mr. Schwerner had gone to Mississippi with his wife, Rita, in January 1964, having been hired as a CORE field worker.
Field strengths larger than roughly 105 G can produce the observed depression, and in one case a core field strength of 107 G can be measured.
The geometrical factor is indeed equal to 4500; the downward continuation to the CMB of a core field contaminated by crustal anomalies is known to require some precautions.
Here, our main goal is to investigate how well one can control a core field model by applying constraints on the co-estimated flow model.
Two distinct approaches are integrated in the dedicated core field modeling for Swarm, estimating a core field and estimating the Euler angles.
As a consequence, it is preferable to use either the full CI model or a dedicated core field model together with an additional model for the ionospheric field (Chulliat et al. 2013), to ensure that the contribution of the ionosphere induced in the Earth's mantle is also corrected for.
For example, a release of version 1 of a Dedicated core field model valid from midnight on 01 June 2013 to midnight 01 June 2014 would have the following file name: SW_OPER_MCO_SHA_2D_20130601T000000_ 20140601T000000_0001. Before a Level 2 CAT-1 product file is released to the general community, it undergoes a number of checks carried out by an independent partner within L2PS.
As an implication to Mars and in the range of our model, the study concludes that an ancient core field modified by a CMB heat flux anomaly is not able to heterogeneously magnetise the crust to the present-day level of north south asymmetry on Mars.
This way, we allow for a better description of the external field at mid latitudes which, ultimately, leads to a better core field model quality.
In order to obtain a robust core field model for the entire data time span, constraints have to be applied on the model parameters.
