[yt-users] Plotting particles only above a certain mass

Dear wonderful YT genii, Within the star particle routine I am using, when star particles merge they are kept and have mass set to tiny_mass rather than being deleted. This makes keeping track of specific particles easier but makes plotting harder. Does anyone have any good ideas for how to modify or create a new p.modify["particles"] that will only plot particles above a certain mass? many thanks, Libby -- Elizabeth Harper-Clark MA MSci PhD Candidate, Astrophysics, UofT www.astro.utoronto.ca/~h-clark h-clark@cita.utoronto.ca AIM: edphc1 MSN: edphc1@hotmail.com Skype: eharperclark Office phone: 416-978-5759
