\Con"stant\, n.
1. (Astron.) A number whose value, when ascertained (as by
observation) and substituted in a general mathematical
formula expressing an astronomical law, completely
determines that law and enables predictions to be made of

of a substance or of an instrument of precision; as, the
dielectric constant of quartz; the collimation constant of
a transit instrument.
{Aberration constant}, or {Constant of aberration} (Astron.),

aberration enables a prediction to be made of the effect
of aberration on a star anywhere situated. Its value is
20[sec].47.
{Constant of integration} (Math.), an undetermined constant
