Module bc_conversion 

Ballistic-coefficient conversion between standard reference drag families (MBA-1375).

A reference-family BC appears in the point-mass retardation as Cd_ref(Mach) / BC. Consequently, conversion at one Mach is an exact table-ratio operation, while fitting one scalar BC across velocity bands is a one-parameter least-squares problem in reciprocal BC. This module owns that shared, filesystem-free math so native and WASM front ends cannot drift.

Structs

BandedBcConversionV1

A velocity-banded conversion into one requested target family.

BcFamilyFitV1

One candidate family’s best single scalar BC over a source band schedule.

BcFamilyRecommendationV1

Ranking of candidate families by their one-scalar fit to a source band schedule.

BcSegmentAnalysisV1

One banded operation’s requested conversion and family recommendation.

BcSegmentConversionV1

One input BCSegmentData band converted to a constant BC in another family.

ScalarBcConversionV1

Exact conversion of one scalar BC at one Mach number.

Enums

BcConversionError

Why a BC conversion or family fit was rejected.

BcConversionFormat

The canonical output forms shared by native and WASM front ends.

BcConversionReportV1

Type-erased report accepted by the shared renderer.

Constants

BC_CONVERSION_SCHEMA_VERSION_V1

Schema version carried by every serializable conversion report.

MIN_BC_CONVERSION_TABLE_POINTS
