Tilt notation

[svvenkatakrishnan]

From multiple user experience, the software has the tilt notations upside down. What we call X tilt should apparently be Y tilt.

Is this for FEI data or just in general?

[svvenkatakrishnan]

In general apparently. The users say that the way our data tilts, if we call left to right X and top to bottom Y, then its tilting along the Y-axis and is called Y tilt.

Either Larry did not notice it or else he 2 users who mentioned it to me are wrong. Why dont we hold this back till I speak to Larry and verify it.

I swapped the FeiHeader.a_tilts and FeiHeader.b_tilts and the GUI's now show the tilts in the "Y" column but the actual display will still look like the rotation is about the a vertical axis. This also gets down to how someone is referring to the rotation. i find that about 50% of the people get it wrong when trying to describe a "vertical" axis and really mean a horizontal axis. You need to get the users to describe with pictures exactly what they mean. Then we can make the GUI match what they want.
