Data organization
See table below for relevant zVariables stored in the CDF file. Each CDF record contains one vector.
| NAME | TYPE | UNIT | DESCRIPTION |
|---|---|---|---|
| Epoch | CDF_TIME_TT2000 [1] | ns | Epoch time of the record. Acquisition time of sample. |
| SCPOT | CDF_FLOAT | V | Spacecraft potential with respect to plasma. |
| PSP | CDF_FLOAT | V | Average probe-to-spacecraft potential. |
| QUALITY_FLAG | CDF_UINT1 | Numerical flag in the range 0-4 to indicate the quality of the data. Higher is better. | |
| QUALITY_BITMASK | CDF_UINT2 | Quality bitmask to indicate various quality-related conditions specific for L1 processing. The values are inherited from the parent data products. | |
| L2_QUALITY_BITMASK | CDF_UINT2 | Quality bitmask to indicate various quality-related conditions specific for L2 processing. The L3 data products inherit the values from the parent L2 data products. | |
| DELTA_PLUS_MINUS | CDF_INT8 | ns | Half the sample integration time. Half the bin size for downsampled data. |

Caveats and known issues
Table below gives the list of main known issues and the actions taken to mitigate them.
Please read the CAVEATS global attribute entries in the CDF files to be aware of the possible issues and limitations concerning data.
| ISSUE | MITIGATION(S) |
|---|---|
| RPW MY (3) electrical antenna signal was lost intermittently between November 13th and March 15th. Corresponding BIAS data were impacted. | None yet. Data products for the affected time interval are not yet available. Future data products will have a specific entry added for the global attribute CAVEATS and zVariable QUALITY_FLAG zVariable capped at 1 for impacted records. |
Release notes
See MODS global attribute in the CDF files for an history of the data modifications.
