Find the best Dispersion Measure for a pulse by maximising the coherent power accross the bandwidth. It is robust to complex burst structures and interference.
The necessary dependences will be installed automatically, except psrchive (see Prerequisites).
Run python DM_phase.py -h for a list of arguments.
Basic example: python DM_phase.py fname, where fname is the filename of a PSRCHIVE object.
Alternatively, it is possible to run the function get_DM on a 2D numpy array representing the pulse waterfall.
See the function documentation for details.
Python module of psrchive is required to read PSRCHIVE files and it will not be installed automatically. See the package page.
pip install DM_phase
