| 英文摘要 | Phoebe was observed in 2023 and 2024 by Yunnan Observatory 1.0 m telescope. These observations, along with those obtained from 2011-2014 by Yunnan Observatory 2.4 m telescope, were processed using the Gaia DR3 star catalogue. To improve positional measurements, the two-dimensional Gauss fit or the effective point spread function was applied. During the reduction, the geometric distortion of the calibration field was solved, the precision premium was reduced, and the differential colour refraction was accounted for. A total of 368 CCD observations were obtained. The theoretical position of Phoebe was derived from IMCCE ephemeris ph12 and Saturn's position from JPL ephemeris DE441. The results show that the mean (O-C) is-0.002 and 0.016 arcsec in right ascension and in declination, respectively. The dispersion of our observations is 0.028 and 0.028 arcsec in right ascension and in declination, respectively. |
