Help with camera gain electrons per data number

tennyson

I am relatively new to this hobby so please bare with me if this a stupid question.

I have a ZWOASI 2600 and am trying to preprocess an image in Pixinsight.

In the Subframe Selector Module one of the parameters require the camera gain electrons per data number.

Please could someone advise what this is and the value for this camera.

Thanks.

In https://astronomy-imaging-camera.com/product/asi2600mc-pro-color , scroll down to "Camera Performance". The second graph shows the dependence of gain (e-/ADU) from the gain setting in the camera driver . With this camera, you probably want to use either a gain setting of 0 (= about 0.77 e-/ADU) or a gain setting of 100 (= about 0.25 e-/ADU). The gain setting can be set in the acquisition software / camera driver settings.
