This will give a number of equivalent bad scans. The distribution of filled minor frames is characterized as being either clustered or scattered.

The image quality is based on the number and distribution of bad scans or equivalent bad scans in a scene. It is computed by dividing the total number of filled minor frames for a scene by 6313 (the nominal number of image data minor frames in a major frame for 30 meter bands). This will give a number of equivalent bad scans. The distribution of filled minor frames is characterized as being either clustered or scattered.
