RAW data

The RAW data is a three-dimensional image, which is slightly reduced from the original product generated by Tomo-e Gozen. The differences between RAW data and the original product are tabulated below.

	RAW data	Original Product
Image Size	2156×1128	2160×1200

Since part of reference pixels are chopped off, the image size of the RAW data is smaller than that of the original product. Note that the image size can be changed in the partial readout mode. The bias pattern is subtracted in the RAW data. Refer to Bias Subtraction section for details of the bias subtraction.
