      Description

      Some gains are zero, that's bad (leads to inf variance, and therefore NaNs).

      The other values are meaningless as this is currently being used for any given raft, so lets set them all to 1 for now. Also set all the readNoise values to 10 for now.

          The choice of gain of 1.0 is natural.  We discussed setting the readNoise to 0.0 or to a plausible-but-possible-confusing value of 10.0.   We decided that we were scared that someone somewhere would set the variance to inf if we didn't have some read noise (e.g. for bias frames); hence 10.0
