Spherical harmonic model of the gravitational potential of Ganymede from Gomez Casajus et al. (2022)

Ganymede2022 is a spherical harmonic model of the gravitational potential of Ganymede that makes use of data from Galileo and the JUNO extended mission. The data in the file Ganymede2022.sh.gz are identical to those in the submission 6949645 (Gomez Casajus et al. 2022) with the exception that they have been reformatted in a way that facilitates their reading by the python package pyshtools, and the GM has been included (personal communication from the original authors).

Ganymede2022是一款针对木卫三（Ganymede）引力势的球谐模型，依托伽利略号探测器（Galileo）与朱诺号（JUNO）扩展任务的观测数据构建。文件Ganymede2022.sh.gz中的数据与提交编号6949645（Gomez Casajus等人，2022）中的数据完全一致，仅进行了格式重构，以方便Python工具包pyshtools读取，且补充了原始作者私人通信提供的引力参数GM。
