Dear all,
    I'm doing Hg SAD phasing for the first time, and I met some problem:
1. How to assess the anomalous signal after I process the data and get my mtz file?  
    My labmate doesn't scan the fluorescence signal. Actually, I don't quite understand why we use fluorescence to detect anomalous signal.
2. How to estimate the number of heave atom in one unit cell? by soaking heavy atom derivatives.

Best!
