This is the wavefront error. See http://www.telescope-optics.net/aberrations.htm for more information.

Note the manufacturer must state whether 1/12 or 1/16 is peak to valley or average to peak. The difference is 2x.

Note I normally deal with BINTEL and I know the staff there know their products very well. The pricing is reasonable and after sales service second to none.
