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,144,1146,1Here 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.
