Final 3D Vs model and dispersion data for the paper entitled "Crustal velocity images of north-western Türkiye along the North Anatolian Fault Zone from transdimensional Bayesian ambient seismic noise tomography". In the vel_files folder, there are 10 files for each depth for 1-15 km. The format of each velocity file is as follows: Column Value 1 Lattitude (°) 2 Longitude (°) 3 Vs (km/s) The format of the dispersion data is as follows (See Computer Programs in Seismology Tutorials - do_mft for more information on the format): Column Value 1 Type of file, MFT96 2 Wave type: R for Rayleigh 3 Dispersion type: U for group velocity 4 Mode: 0 represents the fundamental mode 5 Filter period, T, in seconds 6 Dispersion value, either group or phase 7 Error in dispersion. This is just a place holder since there is no way to estimate an error from a single trace. The group velocity error is determined from the ratio of the filter period to travel time 8 Distance in km 9 Azimuth from the source to the receiver 10 Spectral amplitude. 11 Epicenter latitude 12 Epicenter longitude 13 Station latitude 14 Station longitude 15 control flag 16 control flag 17 Instantaneous period if this is preferred. This differs from the ilter period because the signal spectram is not flat. 18 Comment: keyword 19 Station 20 Component 21 Year 22 Day of year 23 Hour 24 Minute - these identify the event origin time
