How to define cloud types in cam5?

Hi everyone,
I've noticed that in the output files of CAM5, variables about cloud fraction include cloud fraction and vertically-integrated high, mid-level and low clouds. There're 30 vertical levels, and I'm wondering how to define different types of clouds. In which pressure levels that these clouds could be defined as high, mid-level or low clouds? Thanks.

This information is buried in the code unfortunately (/src/physics/cam/cloud_cover_diags.F90)

parameter (plowmax = 120000._r8,plowmin = 70000._r8, &
pmedmax = 70000._r8,pmedmin = 40000._r8, &
phghmax = 40000._r8,phghmin = 5000._r8)

So CLDLOW = 1200-700mb, CLDMED=700-400mb and CLDHGH = 400-50mb

(we should put this in the long name of the history field, but we do not)
