<dd>Adds an auxiliary reflection with indices qh, qk, ql to the list. A4 is
|

calculated from cell constants. A3 is either left alone or is calculated to
|

have the correct angular difference to a previous reflection. This is a help

for setting up the instrument or running powder mode. When a UB has been
|

generated from auxiliary reflections, a3, sgu and sgl angles will be incorrect.
