 MOSTAB: Invokes a menu to change the MOSTAB (monochromator stabilizer) settings (6.8). The upper part of the widget contains buttons that send MOSTAB commands to the device.

The middle part of the widget is used to specify the setpoint, e.g. 70% and 'Left edge'. There is also a button that sends the current setpoint selection to the MOSTAB, 'Send Setpoint'.

The third labframe contains checkbuttons for the 'Analog', 'Use I1', 'Peak search before scan' and 'Use MOSTAB' flags. Changing one of these flags, has no immediate effect. It is is relevant for scans only. The flag 'Use I1' determines whether I-Doris is used by the MOSTAB at all, 'Analog' selects how I-Doris is supplied, by an analog voltage which is delivered via cable or by a digital value which is read from a server. 'Peak search before scan' is normally enabled. However, there are cases when users want to disable this feature. 'Use MOSTAB' is the main switch that determines wheter the MOSTAB is operated during scans. This flag shadows the corresponding flag of the scan widget. Depending on the status of 'Use MOSTAB' the other three flags are disabled or not. Note that, if the 'Use MOSTAB' flag is changed from the scan menu, the three flags are not updated.
