Hello. I understand that the pixel scale of the ATR294C is 4.63 in 14 bit. But what is the pixel scale and bit depth in hardware binning mode for each of bin 1, 2, and 3 averaging method please? Please be detailed. A chart would be useful too. Thank you.

1 Description and Features The ATR294C(ATR3CMOS10300KPA) camera is designed specifically for astrophotography. It is mainly used for deep sky photo shooting, since the camera has cooled CMOS sensor, ultra-low readout noise and low amp-glow. It can be also used for planetary photo shooting.
Windows® XP / Vista / 7 / 8 / 10 / 11(32 & 64 bit) Supported OS OS x (Mac OS X) Linux 2.2 Sony IMX294 Sensitivity The sensor G Sensitivity of ATR294C is 419.02mv with 1/30s. Its spectral sensitivity is shown in Figure 2.
2.3 14bit ADC and ROI ATR294C has built in 14bit ADC. It also has 12bit output mode for hardware binning and smaller resolution. The camera also supports hardware ROI, and the smaller the ROI size is, the higher the frame rate is.
2.8 Low Amp-Glow ATR294C has been carefully designed and is able to achieve low amp-glow photo shooting. Figure 3 and Figure 4 show the different cameras at 20C and 5-minute exposure time with high amp glow and low amp glow. By comparison, the image captured by ATR294C shows low amp-glow.
