When Plate Solving with GAIA DR1 from Vizier is done, the chart with the red stars (right side in picture Gaia-solving.jpg) is rotated anti clockwise 90 degrees.
The orientation of the North-East Arrows on the Plate which is solved (left in the picture) is also rotated, North to the left, but real North is at top. Solving works, but not very well.
With UCAC4 it works fine.
What can be the cause o this?
