[daip] dbcon on different polarization datasets?

[Susan Neff]

Hi Eric,

I'm trying to concatenate several UV data sets from 
pre-EVLA data.

They started out from the same observations, but were 
split apart
earlier in the processing, to be IFs 1 and 2, and 
polarizations RR
and LL, so 4 separate UV datasets (long story).   They 
are not
polarization observations - I'm just trying to use 
IMAGR to make
a total intensity image.

I can get DBCON to combine the IF1 and IF2 for each 
polarization,
by relaxing the dopos constraints.  However,  I can't 
get it to
combine the RR and the LL.  I get an error message saying:

localh> DBCON1: STOKES RANGES DO NOT OVERLAP
localh> DBCON1: Purports to die of UNNATURAL causes

Is there a way around this?   Would I cause horrible 
things
to happen in IMAGR if I brute-force changed the 
polarization
values in the headers?


Sorry if this is a dumb question, and thanks for help,
Susan
