[daip] UV amplitudes X100??

[AIPS en Tuktoyuk]

good afternoon,

from the original interferometer UV data I created a dirty map with IMAGR 
(niter=0), and the map looks like it should dirty.  Then using IM2UV I fourier 
transformed the dirty map back to the UV plan.  The original UV data had a max 
amplitude around 12Jy while the IM2UV version has a max amplitude around 1200Jy, 
wow. Do you know why this happened?? Why 100X rather than another multiplication 
factor??

As per the image brightness: the original dirty map has a max of ~0.5899Jy/bm 
and a total flux of ~0.069Jy.  When I use UVMAP on the IM2UV set to transform it 
back to the image plane the image has a max of 0.969Jy/bm and a total flux of 
2.00Jy.  this equals to the total flux being ~29X larger in the new map from 
UVMAP.  I assume this is directly related to the increase in the different UV 
data sets, true??

Is this due to a normalization factor of the FFT and inverse FFT of AIPs?? Or is 
it something else??

Thanks as always for your great help,
sincerely
