| Description: The kernel_provenance attribute indicates whether a kernel file is a predict kernel, a reconstructed kernel, some combination of the two, or a kernel for which the distinction is not applicable. |

| Permissible Value(s) | Value | Value Meaning |
| | Mixed | This kernel contains both reconstructed and predicted portions (e.g. a reconstructed spacecraft trajectory SPK with a run-out predicted tail). |
| | Predicted | This kernel is a predict kernel (e.g. a pre-encounter predicted spacecraft trajectory SPK ). |
| | Provenance Not Applicable | This kernel does not fit into any of the other categories (e.g., LSKs, SCLKs, text PCKs). |
| | Reconstructed | This kernel is reconstructed based on improved information (e.g. a post-encounter reconstructed spacecraft trajectory SPK based on improved navigation information). |
