| + Add an auxiliary reflection to the list of reflections. A4 is calculated from the cell |
| + constants, the current ei and ef values are used. A3 is left alone or is calculated to |
| + have the right angular difference to the previous reflection. Using auxiliary reflections |
| + is a help during setup of the instrument or in powder mode. The sequence: |
| + {{{ |
| + ref clear |
| + cell aa bb cc alpha beta gamma |
| + ref aux ax ay az |
| + ref aux bx by bz |
| + makeub 1 2 |
| + }}} |
| + with ax, ay, az being the first plane vector and bx, by, bz being the second plane vectors achieves |
| + creates a UB matrix which allows to drive QE positions and qm. But be aware that a3, sgu and sgl values |
| + are still invalid. |
