The Determination of the Principal Nutation Terms From the Observations With ZTF-135 in 1948.7-1989.0
Published online by Cambridge University Press: 19 July 2016
Abstract
A re-reduction of observations made with ZTF-135 in Pulkovo during 1948.7-1989.0 (all together about 87 000 observations) has been carried out with the aim of determing the amplitude of the principal terms of nutation in longitude and obliquity. The derived coefficients of nutation M=6.“8445±″0033 and N=9.”2028±0.″0025 are in good agreement with similar astrometric determinations.
