Cross Track Position (CTP) are screened and data from affected CTP are replaced by fill values. Affected CTP are determined by running means for UV Aerosol Index. A 5-point running mean for CTP 2 - 57 (0-based) and a 4-point running mean for CTP 1 and 58 are calculated. CTP 0 and 59 are not screened. If a running mean is greater than 5, the center CTP of the running mean is replaced by a fill value. Overpass data report the closest pixel to the station with "good" data only!
