  • CMB large scale anomalies code: A Python package for computing various large-scale anomaly estimators in Cosmic Microwave Background (CMB) data as described in Testing Cosmic Microwave Background Anomalies in E-mode Polarization with Current and Future Data (Shi et al. 2023). It includes tools for analyzing (1) Lack of correlation, (2) Quadrupole-Octupole alignment, (3) Odd-parity asymmetry, and (4) Hemispherical power asymmetry.
  • Polarized millimeter-wave atmospheric emission model code: This code serves as a supplement to the paper titled Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: A First Detection of Atmospheric Circular Polarization at Q Band. It simulates millimeter-wave atmospheric emission, including polarization. This emission is primarily from molecular oxygen, with emission by water vapor and the dry continuum also considered.
  • Clee-fast code: First release of code that allows for quick interpolation between Cosmic Microwave Background polarized power spectra as a function of scalar fluctuations, tensor fluctuations, and the optical depth to reionization. This code serves as a supplement to the paper titled A Projected Estimate of the Reionization Optical Depth Using the CLASS Experiment’s Sample Variance Limited E-mode Measurement. Note: clee_fast is also available on Github.
