    I have a question about the seismic data set of the 3D survey of Ten noorden van de Waddeneilanden. It seems that the coordinates are missing. Generally, the coordinates are present in byte ranges 73 - 85 and/or 181 - 185 of the header of the seg-y file, however there are no values for coordinates present in these byte ranges. How can we load the data in a seismic interpretation software package?

        CDP-x and CDP-y are mapped within bytes 197 and 201 respectively – format IBM Float 4. More information on the data is available in chapter 7 of the processing report of the 3D geophysical data which can be found in the appendix 1 of the UHRS 3D Preliminary Assessment of Potential Geohazards report. A readme file with the information to load the 3D geophysical data will be added to the 3D data folder on the HDD for easy reference.
