obspy.io.segy.segy._internal_read_su

_internal_read_su(file, endian=None, unpack_headers=False, headonly=False)

Reads on open file object and returns a SUFile object.

Parameters:

• file – Open file like object.

• endian (str) – String that determines the endianness of the file. Either ‘>’ for big endian or ‘<’ for little endian. If it is None, obspy.io.segy will try to autodetect the endianness. The endianness is always valid for the whole file.

• unpack_header (bool) – Determines whether or not all headers will be unpacked during reading the file. Has a huge impact on the memory usage and the performance. They can be unpacked on-the-fly after being read. Defaults to False.

• headonly (bool) – Determines whether or not the actual data records will be unpacked. Useful if one is just interested in the headers. Defaults to False.
