Alert level B THETM01_ALERT_3_B The value of sine(theta_max)/wavelength is less than 0.575 Calculated sin(theta_max)/wavelength = 0.5680
Author Response: The diffractometer Gemini used for the data collection has two X-ray tubes, Mo and Cu. The collimator of Mo tube limits the maximal theta angle of CCD detector and the required resolution cannot be easily achieved with Cu radiation. In order to achieve resolution 0.83 instead of 0.85, several hundreds of frames would be added to the experiment or we would need to measure with removed Mo collimator; the first way is not efficient, the second one is unsafe. Because the sample was weakly diffracting and the obtained resolution is not very far of the requirement we used the normal data collection mode.
