                         describe the numerical problems tackled when the INPE's 
                         atmospheric correction system was implemented. There are two types 
                         of problems: a) results accuracy, and b) excessive number of 
                         operations. The accuracy problem is solved by usino the Burroughs 
                         B-6800 to compute the atmospheric transmittance. To reduce the 
                         number of operations, the use of precalculated tables is 
                         introduced, instead of actually doing the operations.",
