[daip] Re: [Fwd: DBCON Frequency Warning (fwd)]

[Eric Greisen]

This warning is serious.  Programs like IMAGR need to know a
correction to apply to the u,v,w of IF1 to get the u,v,w of IF2.  To
have some but not all of the data at a divergent frequency in IF2 will
cause this operation to be incorrect.  The error in frequency is 140
MHz or 10% of the center frequency which is serious.

You can SPLIT the data into separate IFs making 6 data sets.  These
than can be DBCONed.
