- Halo finding and mass functions
- Particle mesh operations
- Mock catalog generation
- MPI parallelization

## Usage Guidelines

1. **Data Loading**: Load simulation or survey data
2. **Power Spectrum**: Estimate power spectra with FFT methods
3. **Correlation Functions**: Compute two-point correlations
4. **Halo Catalogs**: Work with halo finder outputs
5. **Mock Generation**: Create mock galaxy catalogs

## Tools/Libraries

- nbodykit
- Corrfunc
- halotools
