Constants

DEFAULT_HIT_RADIUS_M

Default hit-zone radius (meters) around the point of aim at the target plane — a 30 cm circle. Shared by the CLI, FFI, and WASM so “hit probability” means the same thing everywhere.

MAX_TRAJECTORY_POINTS

Hard ceiling for points retained by a single TrajectorySolver result.

TARGET_NOT_REACHED_SENTINEL_M

Vertical-position marker for a Monte Carlo sample that never reached the target plane.

Functions

calculate_zero_angle

calculate_zero_angle_with_conditions

estimate_bc_fit

Estimate a BC by fitting a simulated trajectory to measured data, for a chosen drag model (G1, G7, …) and fit basis (drop or velocity). Uses a coarse 0.01 sweep over plausible BCs followed by a 0.001 local refine around the coarse best.

estimate_bc_from_trajectory

Estimate a G1 BC from a drop curve. Back-compatible wrapper over estimate_bc_fit; points are (distance_m, drop_m).

interpolate_powder_temp_curve

Interpolate a muzzle velocity (m/s) from a measured powder-temperature curve at temp_c (Celsius). curve is (temperature_celsius, velocity_m_s) points; it is sorted ascending by temperature before use. Values below the first point or above the last are CLAMPED to the endpoint velocity (no extrapolation beyond measured data), and segments are linearly interpolated. A single point yields a constant.

run_monte_carlo

run_monte_carlo_with_direction_std_dev

Run Monte Carlo with an independent wind-direction standard deviation in radians.

run_monte_carlo_with_wind

run_monte_carlo_with_wind_and_direction_std_dev

Run Monte Carlo with explicit base wind and independent direction uncertainty in radians.
