The slopes of ADEV for the different noises can be converted to slopes 
in MDEV. It is the separation of white phase modulation and flicker 
phase modulation that doesn't go very well with ADEV, but works in MDEV, 
but if you ignore the flicker then you should be able to translate 
without too much difficulty.

Good luck!
