Functions

assign_incident_angle(reflection_angle, ...)	Assign incidence using the closest expected specular reflection angle.
assign_incident_angle_from_shutter_logs(...)	Assign incidence when all shutter states are known and exactly one is open.
closest_beam_incident_angle_graph(...)	Provide incidence assignment using the closest expected reflection angle.
coordinate_transformation_graph(...)	Build the scattering coordinates shared by sample and direct-beam runs.
fixed_slits_incident_angle_graph(...)	Provide a constant incident angle from a single pair of fixed slit openings.
incident_angle(incident_direction, ...)	Angle at which the assigned incident beam approaches the sample.
incident_beam_directions(...)	Compute candidate incident directions from corresponding slit openings.
offspecular_coordinate_transformation_graph(...)	Combine an incidence assignment with the shared offspecular coordinates.
outgoing_direction(scattered_beam, ...)	Unit direction of the outgoing ray at the sample, corrected for gravity.
sample_coordinate_transformation_graph(...)	Extend the scattering graph with the sample's reflection angle and Q.
scattering_angle(outgoing_direction)	Signed elevation of the outgoing ray above the laboratory x-z plane.
shutter_log_incident_angle_graph(...)	Identify candidate beams using each shutter's position and status log.
theta(outgoing_direction, sample_surface_normal)	Specular reflection angle between the outgoing ray and the sample surface.
time_at_detector(event_time_zero, ...)	Detector arrival as float64 seconds since the Unix epoch.
time_at_shutter(time_at_detector, ...)	Estimate the time the event passed the shutter position.
