Data confidence 70 medium

How this score is calculated

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.

Abstract

An approach to solving the problem of monitoring the surface shape of a radiation spot in real time is presented. An analysis of the use of the cross-sectional method to monitor the shape of the surface of a radiation spot in real time has been carried out. The possibility of using the aspect ratio to solve the problem was considered. Experimental studies of the sectional method and the aspect ratio method are also presented.
