It is the number of samples per grid cell, holding the value of the -H command line option. If you run "brlman rtweight" you can read more on what that and other options do. > The region struct seems to have a line of sight value that is expressed in > percentage and is then converted to a factor.

Line of sight or 'los' thickness factor is a uniform modifier of thickness (or density depending on your perspective). It's represented as a percentage so an los of 50, for example, means that even through the in/out thickness of a given ray segment is 200mm, treat it as if it was half that in any calculations (i.e., as 100mm or as something half as dense).
