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

Abstract The results of CCD photometry in the Johnson-Morgan BV R system for the Seyfert galaxy NGC 4151 are reported. The observations were carried out from November 15, 2013 to May 13, 2016 with the 1-m telescope of Tien-Shan Astronomical Observatory of the Fesenkov Astrophysical Institute. An analysis of the light curve of NGC 4151 shows that over the time interval considered the brightness of the object varied synchronously in the three filters with the following amplitudes: ΔB = 0.68 mag, ΔV = 1.09 mag, and ΔR = 1.81 mag.
