It is nice, but:
- 0214 position doesn't exist.
- 0150 & 0200 exact positions are still yet unpublished,
If extracted from the BEA flightplan reconstitued, due to its scale, it is not possible to make any precise position within a margin of error of 3-5 NM.
As I pointed out in the accompanying text, the original 0214z so-called ACARS position first reported by the media was discredited.
I accept that the 0150 and 0200 positions have not been published, but with diligence it is possible to derive them to a reasonable degree of accuracy which assumes that the BEA used Google Earth to construct the graphic in the first place. The BEA graphic provided the first evidence that the 02:10:34 position was not on the ORARO ~ TASIL track, even before I found the French SHOM report and 2.98°N 30.59°W.
Similarly, the 0130 and 0140 positions place the a/c overhead INTOL at 01:32:32.
All that can be deduced so far is that the a/c essentially flew the UN873 center-line plus or minus the plotting error, but that irrespective of that error the 02:10:34 position was 3NM left of track. When the deviation occurred is unknown. It certainly isn't a SLOPS offset (left?).
