Dear Dick:
In order to give you a better idea of the ranges and
distributions of the various kinds of errors that affected
the Enewetak data, I am enclosing a short writeup on that
subject.
I am also enclosing my draft of a proposed Tech
Note descriping how we propagated errors during the cleanup.
If that sounds familiar,
it about two years
doing it.
ago,
it's because you asked me to write
and I've
just now gotten around to
My understanding is that this information on errors will
be presented to
the Marshall
Islands Advisory Group
("Bair
Committee") at the same time as John Tipton's new information
on the soil mass attenuation coefficient.
I believe the idea
is to provide a comparison between the bias due to using the
wrong attenuation, and the random errors that are present.
Please look this material over, and if you have questions or
comments, of if you want more information before the committee
meets to hear Tipton, call me at (702) 736-2293.
Sincerely,
Pidir bond. bez TI Ka
