TITLE:Tilt corrections for normal mode observations on ocean bottom seismic data, an example from the PI-LAB experiment JOURNAL:Seismica PAPER DOI IF KNOWN:https://doi.org/10.26443/seismica.v1i1.196 -------------------- DATA & FILE OVERVIEW -------------------- This dataset contains: Ocean bottom seismometer tilt rotation correction code This is a MATLAB function for tilt correction of OBS data using a simple rotation of the vertical and two horizontals. It minimizes the energy on the vertical component via optimization. To run the code requires the optimization toolbox (function fminsearch). Inputs are X(east), Y(north) and Z(vertical), output are Znew (tilt corrected Z), Xnew (rotated X), Ynew (rotated Y), angy (azimuthal rotation in degrees) and vrt (tilt angle from vertical in degrees).
