Precision of parabolic elements.

BELSERENE E.P.

Abstract (from CDS):

Formulae are given for a least-square parabola on an O-C diagram, with calculation of the parabolic elements and their mean errors. The formulae are applied to TY Sct, an eleven-day classical Cepheid. The resulting rate or change of period is +0.000032 day per year ±0.000016.
