approx_distance Approximate distance for ray turning at the bottom of a layer.
coarse_sample Create a coarse slowness sampling of the velocity model (v_mod).
create_sample Create slowness-depth layers from a velocity model.
depth_in_fluid Determine if the given depth is contained within a fluid zone.
depth_in_high_slowness Determine if depth and slowness are within a high slowness zone.
depth_inc_check Check that no slowness layer is too thick.
distance_check Check that no slowness layer is too wide or undersampled.
find_critical_points Find all critical points within a velocity model.
find_depth_from_depths Find depth corresponding to a slowness between two given depths.
find_depth_from_layers Find depth corresponding to a slowness p between two velocity layers.
fix_critical_points Reset the slowness layers that correspond to critical points.
get_min_ray_param Find minimum slowness, turning or reflected, at or above a depth.
get_min_turn_ray_param Find minimum slowness, turning but not reflected, at or above a depth.

get_slowness_layer Return the Slowness_layer of the requested wave type.
interpolate Interpolate slowness to depth within a layer.
layer_number_above Find the index of the slowness layer that contains the given depth.
layer_number_below Find the index of the slowness layer that contains the given depth.
layer_time_dist Calculate time and distance for a ray passing through a layer.
ray_param_inc_check Check that no slowness layer’s ray parameter interval is too large.
split_layer Split a slowness layer into two slowness layers.
to_slowness Convert velocity at some depth to slowness.
validate Perform consistency check on the slowness model.
