DataStreams: | enaaosuhsasC1.a1 |
Description: | The UHSAS was programmed with a bin sizes appropriate to the aerial UHSAS. This is not really a problem. The bin sizes are not consistent with the other console UHSAS. The problem is in blindly comparing the data between the various UHSAS. This is not a problem of mislabeling or incorrect size bins. The data are correct for the stated size bins. |
