My expression: " RAW mode ", is your: " RAW Data " , in the Capture Option ,
Wich you can see in the files attached, the files captured : Darks and Flats are saved in monochrome file, but the Light capture in color file.
By that my expression: " Raw mode " , because is a different mode to save the file.
For the raw mode, it means the original data which you get from the camera.
It just means the light intensity of each pixel, no other means at all. Usually, it use the gray-scale to represent. At now, you will get a mono image.
For a color camera, different pixel means different color, this step of matching values to colors is called debayer。
After debayer, we knows.
For hardware bin, it just indicates whether the bin operation is executed by the sensor or by our SDK.
