Absolute Magnitude of Solar System Body (H) ↔ Diameter implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Computation or source lookup only

Input and validation requirements

The specification leaves the default albedo value unspecified, does not explicitly state that albedo must be a fraction in the interval 0 < p <= 1, and provides no rejection behavior for p = 0 or p > 1. It also has no genuine piecewise formula branch; the tested switch is only a physical-validity gate.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

  "inputs": {
    "H": 0,
    "albedo_p": 1
  },
  "expected_outputs": {
    "diameter_km": 1329
  },
  "working": "sqrt(p)=sqrt(1)=1.  -H/5=-0/5=0.  10^0=1.  D=1329/1*1=1329 km."
