1. Shutter
The shutter is a two-blade mechanism used to control the duration of the exposure. A listing of the possible exposure times is contained in Table 2.3 . ... However, an exposure time shorter than the minimum allowed (0.11 seconds) is, instead, rounded up to this minimum value. ... Exposure times where the PSF is affected by the shutter blade flight time are underlined and flagged with table footnote (2). ... 2 Exposure times where the PSF is significantly affected by the shutter blade flight time . ...

2. The Mock Spectrometer
... Of the 4 buttons in the bottom part of the configuration screen, three deals with power level adjustments: the 'Power control' button brings up the power control window where You can adjust the power levels of the different parts of the IF/LO system, the 'Power levels' button brings up the power level monitoring window (which also can be run outside CIMA as the 'powerwin' program), and the 'Adjust Mock power' button which adjusts the power levels on the Mock spectrometer (but nowhere else). ...

3. PREEMPT
... PREEMPT is used to allow, or not, scans to be preempted for other purposes. ... PREEMPT = EXTRA tells /schedb and VLBA operations to treat the scans as extras that can be used to help fill gaps between projects that often occur with dynamic scheduling. PREEMPT = NO tells operations not to use the Pie Town and Mauna Kea antennas at the time of the scan for daily USNO Earth Orientation Parameter (EOP) observations. ... The default, 'OK' , means that the scan be preempted and is a ``core'' scan. ...

4. Customisation
... Many options allow to run emchain on a subset of the data, restart from previous output, change the options of constituent tasks. The exposures , instruments and ccds parameters allow to run emchain on a subset of the data files (select an explicit list of exposures, instruments or CCDs). ... This is similar to passing backgroundset to emenergy , but allows to save all such files under a different name. emchain normally ignores data obtained with CCD read-out gain set to low (/10). ...
