v3-fieldmap has survey positions for the SVT. v3-1-fieldmap has, in addition, some Millepede alignment corrections set in the compact.xml. I don't know if the LCDD file was generated in a way that uses these constants, probably it wasn't and somebody who knows what they're doing should run GeomConverter before the LCDD file can be used. But: as long as MC readout and recon use the same alignment constants, it shouldn't matter what they are. So I would recommend using v3-fieldmap.
