Currently MakeCatalog can only make columns that are internally defined for it. The process of implementing a new column in MakeCatalog is not hard and infact we even have a section in the book.

However, ultimately, each pixel only has a position (x,y) and value (v). So it should not be hard to allow the users to define columns at run-time, through a file (for example) with a good sytax to make it easy. In Arithmetic, we already do have a very simple syntax parser for statements which can be used/exteded together with this task.
