NOTE -- reprocessed data using ashtech and again using seapath as accurate heading device; concluded seapath was better. -- incorporated estimated transducer offsets and reprocessed again -- using 'uvship' for navigation rather than 'nav' (traditional, first-differences from last fixes in ensemble) improved underway bias during transits in bad weather PROCESSOR : J.Hummon ============= os75nb dbinfo ================ #this file was automatically generated.
