This table enables to define the parameters of the detector that is used in the radiometry/...power distribution calculations.
The detector has a rectangular shape. Its dimensions along the X and Y axis are defined respectively by the width and height cells.
It can either be a single detector or a multidetector made of several pixels. The number of pixels per line and per column are respectively defined by the pixels per line and pixels per column cells. For a single detector, "1" must be entered in the pixels per line and pixels per column cells.
By default, the detector is located in the observation plane. The position of its center along the X and Y axis is defined respectively by the X decenter and Y decenter cells.
