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

Effective temperature, bolometric correction, radius, angular diameter and luminosity have been obtained for 9 stars of the spectral type A5-G2, belonging to IV and V liminosity classes, by means of the infrared flux method as modified by Blackwell et al. (1980). The comparison of the effective temperature values with those obtained using the calibration of monochromatic flux by Koornneef for J, K and L bands (Koornneef, 1983) and by Johnson for I, J, K and L bands (Johnson, 1966) shows that Teff in Koornneefs calibration are systematically lower with the difference of the mean values for the stars investigated being about 1.6%.
