[AZ-Observing] Re: EW Paper Given at the S-P Meeting in Dewey

All,
I made an error when I was cleaning up the paper. I said on page 6:
"From this it can be seen that at each pixel location the continuum is 
the difference between M and the intensity value at that pixel location 
as a proportion of M, where M=1."
M is not equal to 1. It is the mean of the intensity values in the 
region selected that has no spectral lines. I added this sentence 
subsequent to the presentation, and in my rush to get it out to this 
group I did not catch my error.
