How to find the data belonging to a given reflection hkl in a linear list of reflection data Reflection data assumed in array REFL(I,J) • Option #1: linear search Memory efficient but time inefficient • Option #2: with the help of a 3-dimensional address array Addresses array requires worst case dimensioning Array element ADDR(H,K,L) contains the address I for the data in REFL(I,J) • Option #3: with the help of a linear address array No worst case dimensioning needed
