Empirical Calibrations of the UVBY, Beta Systems - Part Three - the A-Type Stars
Abstract
Photoelectric photometric four-color and HP indices have been calibrated for A-type stars (stars with 2.890 > P> 2.720 and c 1 <0.28 that are not B-type stars) in terms of intrinsic color and absolute magnitude by using data for bright stars and stars in several open clusters. Intrinsic color indices should be predictable to about +0.01 mag and absolute magnitude to + 0.3 mag. Systematic effects can exist in the absolute magnitude calibration due to rotational velocity. Am-type stars appear to fit the calibration well. There is quite a good agreement between the photometric classification and MK spectral classification.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
