| Description: Gain correction in CISSCAL is the first step of converting DN to flux. This step multiplies the image by a gain factor to convert digital numbers (DN) to the number of electrons detected, based on the camera's gain state. CISSCAL automatically selects the appropriate gain factor based on image metadata. |
