New calibrations of blanketing parameters DELTA m2 and delta m1 in terms of [Fe/H].
Abstract
New calibrations are derived for the blanketing parameters Delta m2 and delta m1, of the Geneva and Stromgren photometric system, respectively, in terms of Fe/H. Based on a sample of 164 A-F main-sequence and giant stars, two quadratics relations in a metallicity range from -2.13 to 0.5 are defined.
