P. 1-20. 1991PDRII3077_____T Informations. relative to: planet reference frame: astrometric centre of frame: geocentre epoch of equinox: 0 - J2000, 5 - B1950 time scale: UTC reduction: Catalogue - FK5, Catalogue - FK4 coordinates: X, Y diff. refraction: no information receptor: photographic telescope: Refractor, F = 10.4 m, D = 62 cm observers: Kisseleva T.P., Tolbin S.B. data included in standard data file: no Comments. evaluation: The differences O-C(X), O-C(Y) are published in the article. For these values one have (the 5 positions with gross errors were excluded): X Y M. (mean) 0.061" -0.199" R.M.S. (root mean square) 0.316" 0.385" The differences O-C(X)e, O-C(Y)e were also calculated by N.Emelianov with the theory by Harper & Taylor. With these O-C one have X Y M. (mean) 0.019" -0.175" R.M.S.
