    Thanks nFA - Great article - could you expand on data in the graph? I think I'm picking up what they are putting down...
    would like to get your take, especially where the all 3 lines (observation of NGC 3201, Nbh>200, Nbh<10) come together.

    What the graph says is that where all three come together at radius 100 arc seconds you can't tell the difference between the Nbh > 200, Nbh < 10 and the actual surface brightness data for NGC 3201. But for smaller radii < 100 arc seconds the Nbh < 10 line is ruled out by the NGC 3201 data which agrees well with the Nbh > 200 prediction.

    Much appreciated nFA, thank you - had to make sure.
    Also find some comfort in BH's being retained instead of flung about like cosmic 8 balls - rather a scary thought that...

    I find my neighbor who loses bullets in HIS neighbor's kitchens much more frightening.
