<strong>Tecnai</strong> on-line help Options 98Options Software version 2Angular Error LimitThe angular error limit determines by how much the interplanar angle between the two d-spacingscalculated may differ from the measured angle.OKPressing OK exits the match constraints dialog while keeping any changes made to the values of thematch constraints.CancelPressing Cancel exits the match constraints dialog without changing the values of the match constraints.7.6 Two-zone indexing procedure in stepsThe two-zone indexing procedure can be executed as follows:• Find a suitable first zone on the crystal with the stage tilts.Intermezzo: Making it easier to find a suitable second zone axis• Identify the zone axis and use the Manual indexing method to set the rough orientation of the crystal.• Store the stage position in the Stage control panel.• Change the orientation to a different zone axis on the k-Space display.• Press the Stage To button in the k-Space Control Panel to tilt the real crystal to the new orientation.• Adjust the stage tilts to bring the required zone axis to the center.• Store this stage position also in the Stage control panel.• Go back to the stored position for the first zone axis with the Move To or Go To function of the stage.• When the second zone axis is needed, use the same functions to recall that stage position.End of intermezzo• Press the 2-Zone button in the Crystal tab of the flap-out of the k-Space Control panel.• In the Two Zone Indexing dialog, select a zone-axis memory for the primary zone axis with the spinbuttons and press Calculator for the Primary zone axis.
<strong>Tecnai</strong> on-line help Options 99Options Software version 2• In the Zone Axis Calculator, use the measuring procedure to define two d-spacings and theirinterplanar angle or enter the values by hand (the latter as in the example dialog below).• If necessary, check the Match constraints by pressing the Setup button.• Press the Calculate button. Calculated values will now be inserted and the Resultant Zone axis listwill be filled.• Press OK to exit from the Zone Axis Calculator dialog and go back to the Two-Zone Indexing dialog.
