The quantity 806.6 per millimeter is not 0.806 micron. It is not a length at all. It is a linear density of 806.6 non-dimensional units per mm. You are having what I call a temporary "brain check." Don't worry about it - I have them all the time and still survive as yet. 8^) The term "brain check" I think it comes from the good old days when the "CPU CHECK" light coming on sometimes meant very bad things for a computer. Maybe yours is due to the effects of Frank Grimer's tinkering with dimensional analysis. 8^) Regards, Horace Heffner
