The Data Quality file is an image having the same dimension and size as the Science Data file. Each pixel in the data quality file is a flag used to identify invalid data points. For each pixel, a value of zero in the data quality file indicates that there is no known problem with the corresponding pixel in the science file. If because of data-dropouts the datum has been filled, the data quality value is sixteen. If the datum failed the Reed-Solomon error check, the data quality value is one.
