| Radius | m | Position in ITRF - Radius | 1 | CDF_DOUBLE |
| F | nT | Magnetic field intensity | 1 | CDF_DOUBLE |
| dF_Stray | nT | Magnetic stray fields correction | 1 | CDF_DOUBLE |
| dF_BlochSiegert | nT | Bloch-Siegert correction | 1 | CDF_DOUBLE |
| Flags | - | Binary combination of the values taken by Flag_outlier, Flag_magnetic_condition, Flag_heater and Flag_step | 1 | CDF_UINT1 |
| Time_piezo | UTC | Timestamp of ASM motor activations | 1 | CDF_EPOCH |
Flags is stored as a 8 bits unsigned integer and can nominally take values from 0 to 15. This number can be written in a binary form such as Flags = '0000abcd', where:
