[alma-config] DOTS image

[John Conway]

Hi,

 I have produced a single pointing field  'dots' 
image which I have given to  Steven to carry out
simulations on. It can be viewed at

http://www.oso.chalmers.se/~jconway/ALMA/DOTSIMAGE/

It is only semi-realistic since all sources are 
points, when most would be resolved in A and B array -
but the source counts are close to those 
expected/observed at 345GHz, N(>S) > S^{-1.1)

More details of the image parameters can be found at the 
above WWW page.

I see the main purpose of this test to see how the 
arrays respond observing a set of compact components 
rather than model sources with extensive smooth emission - 
I hope that for this purpose its realistic enough.

   John.
