Is the banding correction applied to the ESA products?
The memory effect produces light and dark bands in the imagery and is most obvious in homogeneous regions following a sudden transition in intensity, such as at a cloudland boundary. It is also known by other names, including banding, bright target recovery, bright target saturation, scan-to-scan striping, and radiometric hysteresis. Every image pixel is affected and the magnitude of the effect can reach as high as two digital counts. The memory effect has not been observed in bands 5, 6, and 7, which are in the cold focal plane and use preamplifiers that are designed differently compared to those used in TM bands 14. Helder et al. (1997) trace the memory effect to the preamplifiers that amplify the analog signal from each individual detector element. Following saturation by a bright target, the output of the preamplifier undershoots the desired level and recovers exponentially with a time constant of 10 ms, which corresponds to 1040 pixels.
