摘要
鉴于陕西天文台I型光电等高仪(PHA I)目前正在进行暗星观测系统的改装,预期能达到更暗的极限星等。为配合仪器的进展,本文提出了较为灵活的观测星表资料的归算方法,并提出应用PHA I双天顶距观测能开展的主要课题和将来与陕西天文台子午环相配合的课题的建议。
The Photoelectric Astrolabe type Ⅰ(PHA Ⅰ) at CSAO is being reformed for faint star observation. Besides the chain method several other methods could be used in the data reduction for star position corrections, and one of them is proposed in this paper. The PHA Ⅰ will be equipped with a combined prism with two different angles which correspond to two almucantars, so that we could use it to determine absolute declinations of stars and to make a joint program with GMC at CSAO for star position determination and reference system.
