Secular vs Osculating Element Distinction Flag Checker
Bounded declared orbital-element convention distinction, not automatic catalog interpretation.
Description
Secular vs Osculating Element Distinction Flag Checker: look up a supported built-in reference entry.
Osculating elements describe an instantaneous tangent orbit; mean elements describe an averaging convention, while secular terms describe long-term trends.
This tool returns a built-in reference entry for an exact supported selector. The supported entries and their scope are part of the tool; no website or current external table is queried.
When to use this tool
Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.
- Check the supported input and output contract against an existing calculation or observation.
- Use the complete example to confirm units, selector spelling and result interpretation.
How to use the tool and how it works
- Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
Match osculating, mean or secular to its built-in explanatory note.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| elementType | Element type. | Exact value: "osculating", "mean", "secular" |
| elementType | Built-in entry |
|---|---|
| "osculating" | Instantaneous conic tangent to state under a declared force/central-body convention. |
| "mean" | Averaged elements defined by a particular theory/model; not uniquely interchangeable with osculating. |
| "secular" | Long-term trend contribution; not itself a unique full element set. |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.reference | The stored entry for the exact selected key; its type may be text, a number or a list. |
{
"input": {
"elementType": "osculating"
},
"output": {
"result": {
"reference": "Instantaneous conic tangent to state under a declared force/central-body convention."
}
}
}Limitations and assumptions
- The lookup does not convert element sets, average an orbit or select a force model.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
