Inconsistencies in Datasheet Formulas for OP1177 / OP2177 / OP4177

There are few inconsistencies in the "BAND-PASS KRC OR SALLEN-KEY FILTER " section on page 21, Rev. G of this datasheet: http://www.analog.com/media/en/technical-documentation/data-sheets/OP1177_2177_4177.pdf

Formula (3):        Q = K * sqrt(R1 / R2)         is inverted with the formula mentioned later on:  " For Q = 1 / sqrt(2), R1/R2 = 2 in the circuit example. "

Also, the later formula suggests " Select R1 = 5 kΩ and R2 = 10 kΩ for simplicity. " , but, those values do not produce "R1/R2 = 2". And In the schematic  R1 = 20 kΩ and R2 = 10 kΩ.

There's another error in corner frequency for the second stage.  The formula should be:  Fc = 1 / (2 * pi * R * sqrt(C3 * C4))   instead of the existing version with C3 / C4, which cancels the capacitance units.
