The Astrometric Performance Test of 80-cm Telescope at Yaoan Station and Precise CCD Positions of Apophis
Bifeng Guo, Qingyu Peng, Ying Chen +4
The 80-cm azimuthal telescope is newly mounted at Yaoan Station, Purple Mountain Observatory in 2018. The astrometric performance of the telescope is tested in the following three…
Using Gaia DR2 to solve differential color refraction and charge transfer efficiency issues
F. R. Lin, Q. Y. Peng, Z. J. Zheng
The Gaia DR2 catalog released in 2018 gives information about more than one billion stars, including their extremely precise positions that are not affected by the atmosphere, as w…
Investigation and Application of Fitting Models for Centering Algorithms in Astrometry
F. R. Lin, Q. Y. Peng, Z. J. Zheng +2
To determine the precise positions of stars in CCD frames, various centering algorithms have been proposed for astrometry. The effective point spread function (ePSF) and the Gaussi…
Automatic removal of false image stars in disk-resolved images of the Cassini Imaging Science Subsystem
Qingfeng Zhang, Zhicong Lu, Xiaomei Zhou +5
Taking a large amount of images, the Cassini Imaging Science Subsystem (ISS) has been routinely used in astrometry. In ISS images, disk-resolved objects often lead to false detecti…
Characterization of precision premium in astrometry
F. R. Lin, J. H. Peng, Z. J. Zheng +1
Precision premium, a concept in astrometry that was firstly presented by Pascu in 1994, initially means that the relative positional measurement of the Galilean satellites of Jupit…
A distortion solution for the Bok telescope with four CCD chips
N. Wang, Q. Y. Peng, X. Zhou +2
The Beijing-Arizona Sky Survey (BASS) is an imaging survey and uses the 2.3 m Bok telescope at Kitt Peak. In order to tap the astrometric potential of the Bok telescope and improve…
Fringes' Impacts to Astrometry and Photometry of Stars
Z. J. Zheng, Q. Y. Peng
Fringes often appear in a CCD frame, especially when a thin CCD chip and a R or I filter is used. 88 CCD frames of the two open clusters NGC 2324 and NGC 1664 with a Johnson I filt…
Precise CCD positions of Triton in 2014-2016 using the newest Gaia DR1 star catalogue
N. Wang, Q. Y. Peng, H. W. Peng +3
755 new CCD observations during the years 2014-2016 have been reduced to derive the precise positions of Triton, the first satellite of Neptune. The observations were made by the 1…
Precise CCD positions of Himalia using Gaia DR1 in 2015-2016
H. W. Peng, Q. Y. Peng, N. Wang
In order to obtain high precision CCD positions of Himalia, the sixth Jovian satellite, a total of 598 CCD observations have been obtained during the years 2015-2016. The observati…
An improved solution to geometric distortion using an orthogonal method
Huan-Wen Peng, Qing-Yu Peng, Na Wang
The geometric distortion of CCD field of view has direct influence on the positional measurements of CCD observations. In order to obtain high precision astrometric results, the ge…
Preliminary results of CCD observations of Himalia at Yunnan Observatories in 2015
H. W. Peng, N. Wang, Q. Y. Peng
In order to study the potential in high precision CCD astrometry of irregular satellites, we have made experimental observations for Himalia, the sixth and irregular satellite of J…
Phoebe's orbit from ground-based and space-based observations
Josselin Desmars, Shan-Na Li, Radwan Tajeddine +2
The ephemeris of Phoebe, the ninth satellite of Saturn, is not very accurate. Previous dynamical models were usually too simplified, the astrometry is heterogeneous and, the Saturn…
