Image Cube

The Image Cube is a three-dimensional image. Unlike the RAW image, the basic reduction processes (dark, flat) are already applied to the Image Cube. The differences among the Image Cube, RAW data, and the original product are listed below.

Since all the reference pixels are chopped off, the image size of the Image Cube is smaller than that of the RAW data. Note that the image size can be changed in the partial readout mode.
