This device controls the high-level overall focusing of the JHU monochromator. Moving this device will turn blades, cause vertical focusing etc. based on the currently chosen focusing mode. The method of focusing FLAT/ENERGY etc. can be changed through the move device panel.
Also note that the value of this device represents the last known focusing value of the monochromator. If the position of an individual motor is moved this should technically be invalidated, however the position for A1 will still be reported as the original value.

Whenever A1 is moved it moves the blades and other DFM motors to achieve focusing, based on the current focusing mode. Equations describing the motions can be found in the DFM manual. Also, Ei's value is recalculated whenever A2 is moved using the following formula: Ei = 81.81 / ((2 * d-spacing * sin(A1)) ^ 2) or Ei = N/A if A1 is not within tolerance of A2 / 2
