Sentence examples for pick errors from inspiring English sources

As we conservatively assume that traveltime residuals after inversion consist of pick errors, source/station uncertainties, and other noises, we added Gaussian noise, with a standard deviation of 1.1 s, to the synthetic traveltimes.

Gaussian noise with a standard deviation of 1.5 s (equal to the rms residuals after inversion) was added to the synthetic travel times and noise with a standard deviation of 15 km was added to the event locations to perform the pick errors, source uncertainties, and other noises (Pei and Chen, 2012).

We investigate the influences of velocity range constraints and picking errors on the proposed technique.

Figure 11 suggests that increasing picking errors will increase location errors; for example, if picking errors reach 20%% of computed travel times, locations of microseismic events will be poorly constrained.

Therefore, to model our algorithm's sensitivity to picking errors, we add a set of random picking errors to the synthetic arrival times at each receiver, ranging from 0 to 5%% of the calculated travel time.

This can greatly influence the effectiveness of our technique, so it is imperative to minimize picking errors.

Compared with borehole observations, the picking errors of P-wave arrivals are relatively large at the surface.

Figure 9 shows that the perforation shot can still be located close to its true position, despite picking errors.

He said the robots "eliminate the possibility of picking errors" because they scanned the barcodes on the packets.

In addition to estimation errors from the linear inversion, there are other contributions that affect uncertainties: for example, use of incorrect velocity model or arrival time picking errors.

Figure 11 illustrates the relationship between first arrival time picking errors and minimum DDrms values, using the same stop conditions as for the previous tests.
