When setting up a partial frame ROI in WinX/32, keep in mind that for the ProEM the
following constraint applies: the number of pixels in the serial (horizontal) direction must
evenly divisible by 4, even after binning. The software may refer to the horizontal as X or
Wavelength depending on the application.
Examples
These WinX examples include partial frame ROIs with and without binning. The
terminology is based on the WinX/32 Experiment Setup

ProEM System Manual
In LightField, when ROIs are used to acquire data, the ROI parameter
information for ALL of the ROIs is stored in the data file when the data are saved
to disk. You can review this information for the active data display by using the
Show File Information functionality (accessible from the Data Options menu in
the Comparison Viewer.)
NOTE:
For Flatfield Correction, Background Subtraction, etc., the
images must be exactly the same size.
References to X and Y axes assume that the shift register is
parallel to the X-axis and that the data are shifted to the shift
register in the Y direction.
NOTE:
This constraint does not apply to LightField.
X Start to End = 200 pixels, no grouping (binning). Since 200/4=50, this is a valid
ROI setup.
X Start to End = 200 pixels and grouping (binning) is by 8. The resulting number
of super pixels is 25. Since 25/4=6.25, this is not a valid ROI setting for the
horizontal direction in WinX. However, this setting would be valid in LightField.
X Start to End = 240 pixels, no grouping (binning). Since 240/4=60 this is a valid
ROI setup.
X Start to End = 240 pixels and grouping (binning) is by 3. The resulting number
of super pixels is 80. Since 80/4=20, this is a valid ROI setup.
X Start to End = 240 pixels and grouping (binning) is by 16. The resulting number
of super pixels is 15. Since 15/4=3.75, this is not a valid ROI setting for the
horizontal direction in WinX. However, this setting would be valid in LightField.
