obspy.io.segy.segy._internal_read_su¶

_internal_read_su(file, endian=None, unpack_headers=False, headonly=False)[source]¶

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.
