论文摘要
新的彗星目录包含宣布2018年之前发现的近300个长期彗星的数据（代码目录）。这是第一个在动态演化的五个阶段中含有彗星轨道的目录，涵盖了通过围栏的三个连续段落，除了以不同方式处理的双曲线彗星。对于这些长期彗星中的大约100颗，给出了它们的非钻孔轨道，并且为了进行比较，在忽略存在非重力加速的同时获得的轨道。对于许多介绍的彗星，还给出了基于替代力模型或各种位置数据子集的不同轨道溶液。每个彗星总是清楚地指示首选轨道。
The new cometary catalogue containing data for almost 300 long-period comets that were discovered before 2018 is announced (the CODE catalogue). This is the first catalogue containing cometary orbits in five stages of their dynamical evolution, covering three successive passages through the perihelion, except the hyperbolic comets which are treated in a different manner. For about 100 of these long-period comets, their non-gravitational orbits are given, and for a comparison also their orbits obtained while neglecting the existence of non-gravitational acceleration are included. For many of the presented comets different orbital solutions, based on the alternative force models or various subsets of positional data are additionally given. The preferred orbit is always clearly indicated for each comet.
