[mmaimcal] wbs entry, rephrased

[Simon Radford]

Al,

Definition 11 seems to overlap definition 11.1 quite a bit, but covers
the other aspects less thoroughly. Also, don't forget the LSA 183 GHz
system. Here's my rephrasing of some parts:

11 Calibration and Imaging.  This covers aspects of characterizing the
MMA site at Chajnantor, of designing and optimizing the array
configurations, of correcting astronomical observations for atmospheric
and instrumental effects, and of understanding the characteristics and
quality of the images the MMA will produce. 

11.1    Site Characterization includes management and maintenance 
of the site infrastructure, design, development, and deployment of
instrumentation for monitoring of atmospheric conditions, data
collection and analysis, and modeling the effects of the atmosphere on
incoming radio waves.


11.3    Calibration concerns the application of atmospheric measurements
to correct astronomical observations for atmospherically-induced phase
fluctuations and the calibration of signal amplitudes. This includes the
construction ... particularly the 183 GHz systems deployed at the
JCMT-CSO interferometer and by the LSA project at Chajnantor.
