These processed files were examined to assure that the calibration equations were properly
applied, that spans and zeroes gave the correct values, and that anomalies could be accounted for.
Data for each flight were plotted for this purpose. Records of calibrations, instrument status reports,
log books etc. were used to determine time periods when verifiable errors or problems occurred. If
correction of an error or problem was possible, the data file was reprocessed with the correction
applied. The data were then re-plotted to confirm that the proper corrections had been applied. Plots
of corrected SF 6 vs. time can be found in Appendix E. The original data files are maintained
separately.
