Lookup Table of Flow Direction Method

[hoho]

Dear All:

i am recently try to use the Flow Direction funcation to create a Direction GRID,
in my DEM, there are many flat area, i try to understand the Flow in those area,
but in the arcgis help point out that

"???If a cell has the same change in z-value in multiple directions and is not part of a sink, the flow direction is assigned with a lookup table defining the most likely direction. See Greenlee (1987)."

i have downloaded those paper, and unlucky, i don't understand on it,
does anyone can help me to find out those LOOKUP Table or related information,

Thank you very much for all your help

Regards
WK..
