Method Details

[hide private]

get_end(self, site=None)

source code

Do not use this method: use .time_at_instrument() if that's what you want, or use .time_geocent if that's what you want.

Also ... this doesn't return the *end time*, it returns the *PEAK TIME*. You've been warned.

time_at_instrument(self, instrument, offsetvector)

source code

Return the "time" of the injection, delay corrected for the displacement from the geocentre to the given instrument.

NOTE: this method does not account for the rotation of the Earth that occurs during the transit of the plane wave from the detector to the geocentre. That is, it is assumed the Earth is in the same orientation with respect to the celestial sphere when the wave passes through the detector as when it passes through the geocentre. The Earth rotates by about 1.5 urad during the 21 ms it takes light to travel the radius of the Earth, which corresponds to 10 m of displacement at the equator, or 33 light-ns. Therefore, the failure to do a proper retarded time calculation here results in errors as large as 33 ns. This is insignificant for burst searches, but be aware that this approximation is being made if the return value is used in other contexts.
