Cosmic Dawn HI Global Spectrum Experiment Simulation - For Systemic Effects Testing & Foreground Subtraction
This program is used to do below works:
- Single dish radio telescope drift scan simulation,
- Systemic effects simulation, including ionosphere effects, antenna beam distortion, etc.
- Foreground subtraction, so far includes three templates: Polynomial in log-space; EDGES polynomial; model-based SVD.
