the selection function; talking it out

I had a quick call today with Hans-Walter Rix in which we had the millionth conversation about the selection function and how it is used in astronomy problems. And how it ought to be used. We resolved our differences, once again. I think it's important to take any project I'm working on and discuss it over and over again. I learned this from various mathematics colleagues, including Goodman (NYU), Greengard (Flatiron), and Villar (JHU). You don't really understand a project until you can rigorously describe it. And you can only rigorously describe it after quite a few trials and errors.
