Be fair: the engineers are the ones who can't do it this time:  some CCDs
use 3 pixels (RGB) to get color.  Color doesn't come easily, so the actual
focal plane geometry can be a real headache.  1.2 may be the actual "good"
number.  1.3 may indicate some test/autofocus pixels exist along the edges.
All these numbers may be a lie as far as actual monochromatic optical
resolution is concerned at the centers of the R, B, and G passbands.  Pixel
counting is not where most folks really want to go..
