What does the granularity range spectrum mean (units)?

Hello! I have just started playing with Cellprofiler (it’s great!) and have a basic question: for many measurements (e.g. granularity) there’s a range attached (granularity_1, granularity_10, etc.) Are those numbers in units? I’ve noticed at the upper end (12-16) many of my objects measure 0 - did the range get too big?

Many thanks for any and all assistance.

At long last, an answer! CellProfiler Granularity Measurements
