It may be wondered why the data is not recorded over the current
frame period. This action would lead to the display of data which
occurred after the sensor had collected an image. An example is
given of an explosion. In the first CDU image, the display shows
the ball expanding and cracking, but the data shows an explosion.
This is incorrect, because the data is not explained by the image.
In the second CDU image, the data shows the ball expanding and
cracking and this is supported by the data beginning to rise . The
next CDU image correctly shows the ball after the explosion and
the data from the explosion is displayed in this frame.
