High-precision astrometry on the VLT/FORS1 at time scales of few days
P. F. Lazorenko, M. Mayor, M. Dominik +3
We investigate the accuracy of astrometric measurements with the VLT/FORS1 camera and consider potential applications. The study is based on two-epoch (2000 and 2002/2003) frame se…
The Kyiv Meridian Axial Circle Catalogue of stars in fields with extragalactic radio sources
P. Lazorenko, Yu. Babenko, V. Karbovsky +3
A catalogue of astrometric (positions, proper motions) and photometric (B, V, R, r', J) data of stars in fields with ICRF objects has been compiled at the Observatory of the Nation…
Filtration of atmospheric noise in narrow-field astrometry with very large telescopes
Petro F. Lazorenko, Galina A. Lazorenko
This paper presents a non-classic approach to narrow field astrometry that offers a significant improvement over conventional techniques due to enhanced reduction of atmospheric im…
Astrometric precision of observations at VLT/FORS2
Petro F. Lazorenko
In this paper we test the astrometric precision of VLT/FORS2 observations using a serie of CCD frames taken in Galactic bulge area. A special reduction method based on symmetrizati…
