#### Coarse alignment
After the sample transfer the sample stage moved to the measurement position with your new sample. The Xray eye will automatically move in and the shutter will open. You may already see the sample in the omny xeye interface running on the windows computer.
+Height is now centered automatically as part of step 3 below, so manual height adjustment is only needed if the sample is far off screen to begin with:
If you see your sample already at the approximately correct height, you can skip steps 1 to 3. Otherwise adjust the height:
+1. If the sample is far off screen, `flomni.feedback_disable()` then `flomni.umvr_fsamy_tracked(0.01)`, attention: unit <mm>, move the sample stage relative up (positive) or down (negative) until the sample is visible in the xray eye screen, then `flomni.feedback_enable_with_reset()`
1. `flomni.feedback_disable()` disable the closed loop operation to allow movement of coarse stages
1. `umvr(dev.fsamy, 0.01)`, attention: unit <mm>, move the sample stage relative up (positive) or down (negative) until the sample is approximately vertically centered in xray eye screen
1. `flomni.xrayeye_update_frame()` will update the current image on the xray eye screen
+1. `flomni.xrayeye_alignment_start()` start the coarse alignment: mark the sample once to auto-center its height, then measure (clicking in the X-ray eye software) the sample position at 0, 45, 90, 135, 180 degrees. The GUI will present a fit of this data, which is automatically loaded to BEC for aligning the sample.

The functions are safe in the sense that no collisions should occur. E.g. the OSA will be moved back before a movement of the heater.
