If no location or an obviously wrong location is obtained, check print.out. Common problems are:
|Wrong location: Program gets into a local minimum. Use the individual event start location option (`S' in header line). If the problem happen often, try either option for start location (nearest station or start location routine). If dept is the problem, try a range of start depths (set in STATION0.HYP)
|No location: The program iterates outside the maximum distance set for a local or regional event (RESET TEST 57) or the initial start location is outside limits. Use a fixed start location or check readings to get a better start location.
