DATA ACQUIRED FROM MULTIPLE ARRAY CONFIGURATIONS

For uvdata sets obtained from multiple array configuration, one needs to calibrate each array data sets separately. Miriad task invert accepts multiple uv data sets to produce a synthesized image. Users do not have to physically combine the data uv sets prior to imaging. The imaging routines can `internally' combine multiple uv data sets. For two or more uv data sets that are observed and calibrated seperately, this is a way to go. Here is an exmaple of usage:

invert vis=loRes.uvhanning,hiRes.uvhanning       \
       map=helixComb_co2-1.map   \
       beam=helixComb_co2-1.beam \
       imsize=256,256             \
       cell=0.5                   \
       fwhm=1.5                   \
       mode=fft                   \
       line=channel,144,1146,1
Here loRes.uvhanning and hiRes.uvhanning are the calibrated single source files obtained with the same correlator setup using a smaller array and a larger array, respectively. The linetype: line=channel,144,1146,1 allows to combine the two different array's data in a channel-by-channel basis.
