WebIn many land seismic surveys, refraction statics are a key to handling near surface velocity variations. This is especially true in merging complex 3D data-sets, a specialty of Flamingo. In such cases, a velocity model is built … WebIf refraction statics exist and C_STATIC does not need to be recomputed, then you do not need to run this process. Run this process if a change is made to the CDP smoothing, the replacement velocity, the final datum elevation, or the CDP mean computation method. In the refraction statics mode, WebHello Limbus community! Me and several other people have collaborated to bring you all a massive, stage-by-stage breakdown of Refraction Railway in order to try and make sub-120 clearing possible for everyone. We also tried to include information for those looking to further optimize past 120, up to about the 70-turn clear range. tspot locations
