For this step in the calibration process, you choose the number of Bragg rings that you will use to calibrate the instrument parameters. In SAXS mode the minimum is one ring, but if you do not have an entire circle showing, you will need to use at least two. In WAXS mode, the minimum is two rings. In general, the more rings you use, the better the fit, but also the longer it takes.
