...- Static errors resulting from the 3-d inversion are all less than 5 msec. whereas many of those from the 2-d inversion exceed 30 msec. The long-period nature of the 2-d static errors makes it unlikely that they wikk be corrected in a residual statics program. They will instead degrade the data quality...
