We are seeing something odd at the ESRF. We are using the 3 x 3 CCD on I29 This is a tough project, we have to find 80 se. This is the peak below. So far no solution from shelxd Although the R-mrge is OK, we see this dip in CC_anom, for a particular resol range. Is this the xtal or the detector? Does anyone have any suggestions?
