Reassessment of a reported S-delay under Trindade
A correction to a paper by Okal and Anderson (1975) about multiple ScS travel-time anomalies is presented. Data for ScS2 surface bounces in the South Atlantic Ocean have been reanalyzed. From these data an ScS2-S residual of 23.6 seconds was found by Okal and Anderson (1975). This corresponded to an...
