extreme galaxy formation

My day-derailed-off-research-by-undergraduate-studies yesterday was interrupted by a nice talk by Schiminovich about what we have learned from GALEX and Spitzer about star formation in galaxies as a function of galaxy redshift and galaxy specific star-formation rate.

Today I plotted the number of archetypes required to represent a galaxy spectroscopic sample (from Moustakas) as a function of the statistical precision (as measured by chi-squared). The number monotonically increases with the precision, but differently than I expected.
