ABSTRACT. The results of double stars observations at Nikolayev Observatory during 2013-2014 are presented. The Washington Double Stars Catalogue (WDS) was used for observation program composing. The observation volume was obtained with usage two telescopes equipped CCD-cameras. Precise modern epoch CCD-observations allowed to make new proper motion values. The position angles and separations for 214 double stars were measured. Results are going to be submitted to WDS.
ABSTRACT. The results of astrometric reductions of main belt asteroid observations with usage of 3 different reference catalogues are presented. The high precision catalogs CMC15, UCAC4 and GAIA DR1 were used as reference catalogues for calculation asteroid equatorial coordinates. The asteroid observations were carried out at KT-50 telescope of the RI "MAO" Mobitel complex during 2016. The array contains 1666.positions of 68 asteroids mainly in range of (11 -15)
Представлены результаты наблюдений двойных звезд, наблюдавшихся в НИИ «НАО» на протяжении 2013-2016 годов. Выполнена астрометрическая редукция полученных кадров до получения экваториальных координат компонентов двойных и кратных систем на момент наблюдения. Комбинация полученных ПЗС-положений с другими каталогами Страсбургской базы позволили определить новые значения собственных движений наблюдавшихся звезд. Для 214 двойных систем были измерены параметры взаимной конфигурации компонентов (позиционный угол и угловое расстояние). Приведен анализ результатов измерений. Результаты измерений включены в базу каталога WDS. К л ю ч е в ы е с л о в а: ПЗС-наблюдения, астрономические базы данных, визуально-двойные звезды, собственные движения.
Modern astronomical catalogs and sky surveys, that contain billions of objects, belong to the "big data" data class. Existing available services have limited functionality and do not include all required and available catalogs. The software package ACrId (Astronomical Cross Identification) for cross-matching large astronomical catalogs, which uses an sphere pixelation algorithm HEALPix, ReiserFS file system and JSON-type text files for storage, has been developed at the Research Institution "Mykolaiv Astronomical Observatory".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
