Here is the caller graph for this function:

std::pair< StepLimitType, double > genfit::StepLimits::getLowestLimit ( double margin = 1.E-3 ) const

Get the lowest limit.

If hard limits are there, medium limits can be exceeded by up to margin (default margin is 0.1, i.e. medium limits can be exceeded by up to 10%). If no limit has been set yet, return std::pair<stp_noLimit, std::numeric_limits<double>::max>.
