Statistics given are for a bounding box ranging from (51.13N,-1.453E) to (51.17N,-1.413E), centred on (51.15N,-1.433E). This typically encompasses ~12 pixels around Chilbolton in ATSR-2 scenes. Bad matches are ignored. If given as 0 then no good cloudy pixels were found in the search radius.

In colour CTH browse products, grey areas are unmatched and white areas are cloud free.
