[daip] Polarizations?

Hi Andreas,

I have bad news for you.  After being puzzled by your data, I
talked to the analysts (who make the correlator jobs).  It
turns out if the program that generates the correlator jobs
sees only one polarization and is told to do crosspolarizations,
it _copies_ the L polarizations that exist to second fake R
polarizations.  This was done so the case of telescopes (like
VSOP) which only observe in one polarization could be correlated 
telescopes with dual polarization.  So bottom line is that half
of your data is gone.

Sorry about that.  Can you reobserve?

Amy
