Forecast code for: Do Gravity and Geometry Remain Consistently Calibrated? A Test with Gravitational-Wave Distances

Python code used to generate Figure 1 of the paper
"Do Gravity and Geometry Remain Consistently Calibrated?
A Test with Gravitational-Wave Distances".

The script performs Monte Carlo forecasts of constraints on the calibration-drift parameter alpha_M0 using simulated
gravitational-wave standard sirens.

Running the script reproduces the figure and numerical results reported in the paper.
