Probably a bit too early in your "Python career", but you can read raw data 
with numpy. Something like

with open(filename, "rb") as f:
    a = numpy.fromfile(f, dtype=[
        ("distance", "f16"),
        ("iterations", "i2"), 
        ("zc_x", "i2"),
        ("zc_y", "i2"),
    ]).reshape(1778, 1000)

might do, assuming "extended double" takes 16 bytes.
