[yt-users] How to generate ghost zones?

[Kalina Borkiewicz]

I see in the yt 3.3 change log that "ghost zone generation" is a thing, 
but I can't seem to find anything else about this.

I would like to generate ghost zones for FLASH data. I tried 
retrieve_ghost_zones() but that gives an error, and I can't find any 
other ghost zone-related functions. Could I get some advice?

Thanks,
Kalina
