It does not respond to your question about Solaris but I am just curios 
about the logic behind this line of code. Do you really mean to 
calculate a log() of Boolean variable with a result -Inf (for false) and 
0 (for true)? Or is it a typo and you meant (log(abs(rhoStar)) < 1)? 
Then what would be the meaning of a difference between two booleans? Can 
it really be a "SupportRatio" with only three possible values: -1, 0 and 1?

You can just ignore all these questions if you cannot afford spare time.
