This novel receiver-based approach is based on the priciple by Claerbout (1968), which constructes the P reflectivity via autocorrelation. For detailed descriptions, please refer to Sun and Kennett (2016).

If you use the package, the author would appreciate it if you could cite the listed references below.

Put the python source files in any folder you select and add the path to the PYTHONPATH enviroment.

For bashrc,

export PYTHONPATH=$PYTHONPATH:/where/you/put/the/python/files

The way is very convenient for users without root access.

Before you run the example, make sure you have installed the package of OBSPY https://github.com/obspy/obspy/wiki.

First you should import SDI::

import sdi

Then apply these procedures.

sdi.pre-processing()
sdi.autocorrelation()
sdi.moveout()
sdi.stack()

For detailed, please go to the examples folder and check the script of run_sdi.py and plot.py.

The input data should be in SAC format.
