| Description: Refers to the physical units assigned to pixel values after radiometric calibration, and they indicate what kind of brightness or flux measurement the calibrated image represents. There are two possible units: - the standard radiometric units (photons/cm²/s/nm/ster). This is the default if CISSCAL performs the full radiometric pipeline and does not convert to I/F. It reflects absolute scene brightness. - I/F units. This is a unitless ratio that compares the scene's observed brightness (I) to the incoming solar flux (F) at the object's distance from the Sun. |
