But basically: the CT-era sectors by Paranoia Press are the most widely distributed versions and still available (via FFE Apocrypha CDs). Later re-dos by the author (Chuck Kallenbach II) are set a hundred years later than the 1105 baseline for the map and have fallen off the 'net. Whether they align with the DGP dotmaps I'm not sure, but regardless: pending a new publication of the sectors by a Traveller licensee I thought I'd go for the most well-known, albeit apocryphal versions, since the data is unofficial anyway.
