Data type: numb (with optional s.u. in parentheses)
Enumeration range: 0.0 -> infinity
Units: A^-1^ ( reciprocal angstroms)
The reciprocal cell lengths in inverse Angstroms. These are related to the real cell by the following equation: recip-a = b*c*sin(alpha)/V recip-b = c*a*sin(beta)/V recip-c = a*b*sin(gamma)/V where V is the cell volume. Ref: Buerger, M.J. (1942).
