| Corrections | CHG01 | Linear shift applied to selected points. |
| Corrections | CHG02 | Linear drift correction applied to file. |
| fDOM Corrections | CHG03 | fDOM corrected for temperature. |
| fDOM Corrections | CHG04 | fDOM corrected for turbidity. |
| Corrections | CHG05 | Smoothing correction applied to selected points. |
| Quality Flags | QUAL01 | Data flagged as bad. |
| Quality Flags | QUAL02 | Data flagged as questionable. |
| Physical Limits | RM02 | Data removed based on absolute limits. |
| Outlier Removal | RM03 | Data removed based on outlier selection methods and user input. |
| Visualize | RM04 | OOW periods removed based on information from the field form. |
| Data Checks | DUP01 | Duplicated values averaged. |
