## Public Member Functions

CrossingTimeInfo (const double char_speed_crossing_time, const double comoving_char_speed_crossing_time, const double delta_radius_crossing_time)

## Public Attributes

double t_char_speed
t_char_speed is the time (relative to the current time) when the minimum characteristic speed is predicted to cross zero (or zero if the minimum characteristic speed is increasing).

double t_comoving_char_speed
t_comoving_char_speed is the time (relative to the current time) when the minimum comoving characteristic speed is predicted to cross zero (or zero if the minimum comoving characteristic speed is increasing).

t_delta_radius is the time (relative to the current time) when the minimum distance between the horizon and the excision boundary is predicted to cross zero (or zero if the minimum distance is increasing).

bool char_speed_will_hit_zero_first {false}
Extra variables to simplify the logic; these indicate whether the characteristic speed or the excision boundary (or neither) are expected to cross zero soon.

bool horizon_will_hit_excision_boundary_first {false}
