Some thoughts and some new results about the Butcher-Oemler effect
Abstract
These short notes collect some thoughts about the way Butcher-Oemler-like and evolutionary studies are performed. We emphasize the shortcomings of several overlooked technical ingredients in the above type of studies, with the hope of making a useful cookbook for future works. We also briefly report new results of an ongoing Butcher-Oemler study at intermediate redshift.
