So I’m trying to “p.annotate_particles” with RAMSES star particles (over a temperature projection plot) …. But everything in RAMSES is a particle, so when I do 

p.annotate_particles

I end up with a solid black plot… How do I tell annotate_particles to just use the particles with ID < 0 (these are the star particles)??

Thx!
