    While 0.7 out of 1.2 is quite a high error range, I'll simply observe that
    stars in the process of being MatrioshkaBrainIzed *will* be "underluminous"
    in the visible spectrum. I suspect for an advanced technological
    civilization, ~6 light years away is *not* that far if one wants to
    observe a civilization making the singularity transition. (Going back
    to my comments regarding the mass capacity for billions of lunar diameter
    telescopes or their equivalent spread over an even larger area and used
    for interferometric observations.)
