HPGN Datum? (fwd)

[Dean C. Mikkelsen]

Hi Didrik,

15 metres......so we are closer...now I'll lean towards we are off on
one value somewhere - most likely scale.

I'll do some more digging.

Ok, 

I've tested the following :
- removed +long_0
- changed +lat_1 and +lat_2 to the values (taking the lattitudes from
"Parrallèles automécoiques" on the table of your previous e-mail)

That gives the same error, 15 meters on the right of the original
points.
