Pretty darn good M&T, it's great that you've been able to use previous years data as well and just add more to it. It's one of the great things about everything being so far away, it doesn't move much year to year
I agree with you on globular clusters too! Disregarding blue stragglers, given their age they have a peak "blueness" of red as there shouldn't really be any stars larger than 0.8 solar masses.
