依巴谷用浑仪进行测量,至少获得了850颗恒星的位置,但他使用何种坐标系是有争议的。托勒密在《天文学大成》中的星表是从依巴谷星表衍生出来的,给出的是黄道坐标。然而,德兰布雷(Delambre)在他1817年著作的《古代天文学史》(Histoire de l'Astronomie Ancienne)中给出结论,依巴谷知道并使用了赤道座标。但是,奥托·纽格伯尔在他1975年著作的《古代天文数学史》中,对此一结论提出了质疑的挑战。依巴谷似乎用了黄道坐标系和赤道坐标系统的组合:在他对欧多克索斯的评论中,他提供了恒星的极距离,这相当于赤道系统中的赤纬、赤经,混用着黄经、极经度,而不是天球的纬度。
和他的大部分作品一样,托勒密采用,或许也扩充了依巴谷的星表。德兰布雷在1817年对托勒密的作品表示怀疑。《天文学大成》中的星表是否源自依巴谷引起了争议,但是1976年至2002年的统计和空间分析(由罗伯特·罗素·牛顿(英语:Robert Russell Newton)、邓尼斯·罗林斯(英语:Dennis Rawlins)和格德·格拉斯霍夫(Gerd Grasshoff)[9]、基思·皮克林(Keith Pickering)[10]、和邓尼斯·杜克(Dennis Duke)[11]),已经得出结论:《天文学大成》中的星表几乎完全出自依巴谷的星表。托勒密甚至被天文学家(起自1598年的第谷·布拉赫)指控为诈欺(Syntaxis, book 7, chapter 4)所有他观察的1,025颗星:几乎每颗都是使用依巴谷的数据,并依据他的时代2又2/3世纪之后,使用较小的每世纪1°的岁差,将经度增加2°40'。
