News in the CODE Catalogue
Ma{\l}gorzata Kr\'olikowska, Piotr A. Dybczy\'nski

TL;DR
This paper updates the CODE Catalogue of cometary orbits, adding new orbital solutions, considering stellar perturbers, and providing detailed dynamical evolution data for Oort spike comets discovered from 1900 to 2021.
Contribution
It introduces new variants of previous and next orbit calculations, incorporating stellar perturbers and different dynamical models, enhancing the catalogue's accuracy and comprehensiveness.
Findings
Catalogue now includes multiple orbital solutions based on different models.
Previous and next orbits are provided with and without stellar perturbers.
Updated calculations utilize the StePPeD database for stellar influences.
Abstract
We describe here updates and new elements of the Catalogue of Cometary Orbits and their Dynamical Evolution (CODE) that, in its original 2020 version, has been introduced by Kr\'olikowska & Dybczy\'nski (2020). Currently, the CODE Catalogue offers rich sets of orbital solutions for almost a complete sample of Oort spike comets discovered between 1900 and 2021. We often offer several orbital solutions based on different nongravitational force models or different observational material treatments. An important novelty is that the `previous` (at previous perihelion or at 120,000 au from the Sun in the past) and `next` (at next perihelion or 120,000 au after leaving the planetary zone) orbits are given in two variants. One with the dynamical model restricted only to the full Galactic tide (with all individual stars omitted) and the second one, where all currently known stellar perturbers…
