[h] [k] [l] are the hkl values. Parameters of the sample lattice will be set as follows:
A will be set equal to [h]*[lattice constant]/[length]
B will be set equal to [k]*[lattice constant]/[length]
C will be set equal to [l]*[lattice constant]/[length]
[length] is the square root of the sum of squares of [h], [k], and [l]
Alternatively, the user specify combination of symbols A, B and C as parameter of AcceptLattice. A B C refer to lattice vectors A, B and C. The corresponding parameter(s) of the sample lattice will be redefined to the lattice constant determined by the last findpeak command.
