curvature correction

curvature correction

[′kər·və·chər kə′rek·shən]
(astronomy)
A correction applied to the mean of a series of observations on a star or planet to take account of the divergence of the apparent path of the star or planet from a straight line.
(geodesy)
The correction applied in some geodetic work to take account of the divergence of the surface of the earth (spheroid) from a plane.

The ADR36x family of micropower precision band gap voltage references uses a patented temperature drift curvature correction technique that provides a stable output voltage from a minimum supply of 300 mV above the output.
where [delta][x.sub.MI] is the correction from the measuring instrument, [delta][x.sub.r] is the correction from the stylus radius, [delta][x.sub.F] is the measurement force correction, [delta][x.sub.cv] is the surface curvature correction, [delta][x.sub.cc] is the surface concavity correction and [delta][x.sub.ang] is the correction from the surface angle.
The detector features two rotary knobs for easy adjustments and trigonometric flaw location calculations with curvature correction. Four damping settings and eight frequency selections from 250 KHz to 25 MHz enable optimum matching to probe characteristics.
