For any diffraction pattern, using "search and match" in software shows the possible phases (based on restriction). But when we accept a phase We can see the score and scale value. What does it mean ?
The score mean how close the candidate to ur data by peak position and relative intensity ratio. The highest value is 100 (perfect match). But the value wont be rite if ur sample contained rock in dust effect and or preferred orientation, because the database is referred to ideal powder.
