While reading through several articles concerned with mathematical constants, I kept on finding things like this:
The continued fraction for $\mu$(Soldner's Constant) is given by $\left[1, 2, 4, 1, 1, 1, 3, 1, 1, 1, 2, 47, 2, ...\right]$.
The high-water marks are 1, 2, 4, 47, 99, 294, 527, 616, 1152, ... , which occur at positions 1, 2, 3, 12, 70, 126, 202, 585, 1592, ... .
(copied from here)
I didn't find a definition of high-water marks in the web, so I assume that it's a listing of increasing largest integers, while going through the continued fraction expansion.
Is this correct and is there special meaing behind them?
