yes it seems to work. you can check by fixing hypocenter and origin time
and if you then vary the station elevation from say - 999 to +999, you
also see that the travel time changes accordingly. remeber
"altitude in m, in some rare cases, the station is deeper than 1000 m in
which case the minus sign has to
be put in column 1"

Hello,
I would like to relocate some events recorded on ocean bottom seismometers.
I realise that you can input negative station elevations in the control file
STATION0.HYP, but are these elevations actually used in the location
algorithm [even if TEST(40) parameter has been set to 0.0]? i.e. do the
residuals account for the station elevation differences?
Thanks in advance,
Steve
