# Microgram: bicone-hill-profile

`station__algovigilance__microgram-bicone-hill-profile` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Compute Hill activation curve for a width sequence. Models dose-response or signal-threshold behavior at each point along the bicone axis. Returns activation fraction at each position.

## Agent metadata

- `idempotent`: true
- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
- `cost_tokens_estimate`: unknown

## Input schema

- `widths` *object* (required) — Width values along the axis
- `k_half` *number* — Half-maximal width (EC50 equivalent). Default: median of widths.
- `n_hill` *number* — Hill coefficient (cooperativity). Default: 2.0.
