Does anyone have a very clear cut explanation for the above terms? I am unable to understand from the sources in Google. And why a detector is so important in any data reduction program ?
if you want to enter (or stay) in the field, you better try harder. With all the information available online on the topic, even a newbie can succeed in solving some small test structures from single crystal data. Unfortunately most of the young students think that entering a field takes just a few hours or hoping that answers such as "indexing is just the process of assigning hkl values to each spot in a diffraction pattern" . It takes days and nights of hard work to reach the level where you can give a contribution to the research. And I must be honest, but a student coming out with a similar question starts already in the wrong way to be successful in it.
