Marmousi model and data set
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The data by
    Institut Francais du Petrole (IFP)
have been written to the CD-ROM for internal use by
    Vaclav Bucha & Ludek Klimes
    Department of Geophysics, Charles University Prague,
    Ke Karlovu 3, 121 16 Praha 2, Czech Republic,
    bucha@seis.karlov.mff.cuni.cz, klimes@seis.karlov.mff.cuni.cz
during
    November 1999

Data description
~~~~~~~~~~~~~~~~
Please, refer to the accompanying brochure by IFP (1993), and also to
Versteeg (1991, 1993) and Versteeg & Grau (1991).

Data on CD-ROM
~~~~~~~~~~~~~~
The CD-ROM contains the data by IFP modified as follows:
(a) Seismograms located in file "seismic.h@" as the data cube of
    750 time samples * 96 receivers * 240 sources have been splitted
    into 240 data cubes "seis-001.h@" to "seis-240.h@" containing
    750 time samples * 96 receivers for each source.
    The original file "seismic.h@" can be restored by merging
    files "seis-001.h@" to "seis-240.h@" together.
(b) Original big-endian binary data (VAX, Alpha, RISC workstations)
    are located in subdirectory "big", whereas the corresponding
    little-endian binary data (Personal Computers) are located in
    subdirectory "little".
(c) To conform to ISO 9660 and to simplify the portability to a general
    computer system, the filenames have been converted to lowercase
    and the ascii SEP header files "*.h" have slightly been modified.
