small drop out may exist at sh. 1785. Strange ringing noise in center of record. Noise is loud before and after arrival as if not caused by airguns. This is seen other places as well though this is excellent example. Harsh filter bp2-8 can remove some of this effect. Worst noise is between shots 1815 -1850 1st arrival dies out near shot 1850 (~30 km). Stronger "secondary" arrival is present after this Gets very messy beyond 1850 Most of this record crosees east flank of Axial. Bright spot at high end (clearly visible on next record) may be part of a NRZ LVZ. |
