The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 13 new columns ({'Author', 'Altitude Variation of selected/constituent/incorporated trajectories (ft)', 'BFO', 'Lower Bound', 'Imputed Skewness', 'Imputed Sigma', 'Maximum cumulative true track change from 300T @ 1822 in constituent trajectories (Degrees)', 'BTO', 'Imputed Weight (1/sigma)', 'Upper Bound', 'Preference Point if given, or midpoint (imputed xbar)', 'Variation in Ground Track Velocity of constituent trajectories (kts)', 'Maximum time to turn after 1822 (tlatest - 1822) minutes'}) and 9 missing columns ({'Unnamed: 7', 'Unnamed: 1', 'Unnamed: 2', 'Unnamed: 8', 'Unnamed: 6', 'Unnamed: 5', 'Unnamed: 3', 'Unnamed: 4', 'SUMMARY OUTPUT'}).

MH370 Dissertation Working Spreadsheets
Working Excel/CSV files from doctoral dissertation research (Oklahoma State University, EdD) on the MH370 satellite communications data — carrier-to-noise (C/No) and Doppler analysis, antenna gain modeling, BFO/Prx residuals, arc geometry, and a meta-analysis of published trajectory studies.
These are working research files, uploaded as-is. Filenames, (AutoRecovered) suffixes,
and duplicate/dated variants are preserved exactly as they existed in the original research
directory so that intermediate stages of the analysis remain traceable.
