Hello again, I'm trying to implement the variational equations. Based on the example provided in read the docs, I should set the Sun as primary when I do the integration. But I get an error when I try to follow the exmaple shown in the docs. Here's what I'm trying and getting the error with: sim.add(primary=sim.particles[0], "Mercury", date=date) or another: sim.add(primary="Sun", "Mercury") with solar_system_objects = ["Sun", "Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Neptune"]. thank you for your help! about rebound HOT 2 CLOSED

Ok. Thank you!!

You don't need to use primary=sim.particles[0] if you're query solar system data from NASA Horizons. — Reply to this email directly, view it on GitHub<#732 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/AZYVNWLDI6SSRCBPSZV75YTYHCN25AVCNFSM6AAAAABABKQUM6VHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMYTQMZTHE2TINRYGQ>.
