a3, the sample rotation, a4, sample two theta, sgu, upper tilt cradle, sgl, lower tilt
cradle and incoming energey ei and outgoing energy ef.
<dt>tasub addauxref qh qk ql
<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.
