[daip] Re: Galactic Coordinates for SDIMG ?

[Glen Langston]

Hello Eric,

Well, I still hope you are well and enjoying Socorro.
(I've got to get out more...)

Yes there was an error in the data.  However, with that fixed,
SDIMG is still demanding RA.  (PS I've double checked that
the miss-labled RA/Dec form still does work with SDIMG).

Any Suggestions?

Thanks
