r.stream.order: lack of documentation for flow_accum column in attribute table
In NC data set:
g.region rast=elevation
r.watershed elevation thresh=10000 accum=accum
r.stream.extract elevation="elevation" threshold=10000 stream_rast=streams direction=dir
r.stream.order streams=streams dirs=dir vector=stream_order elev=elevation accum=accum
stream_order attribute table now contains a column 'flow_accum'. There is no mention of this column in the man page. What exactly do the numbers in that column represent ?

fwiw, I made some manual calculations in order to establish what the column 'flow_accum' represents. My hypothesis was that it represented the difference between the value of flow accum in the node downstream minus the accum in the node upstream. But my hypothesis was not verified, although the magnitude is comparable. If someone has better ideas I'm ready to test. Thanks
