It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The matrizer method is applied to obtain equations of the wave vector surface and phase velocity magnitude for electromagnetic waves in anisotropic media with rhombic symmetry. Angles of refraction of electromagnetic waves at the interface of anisotropic media are determined, generalizing the Snell law for isotropic optical media.
