Analysis code for the BOSS Even-Parity 4PCF Analysis using encore

Parity-Even-4PCF

This contains the analysis code used in Philcox et al. (2021b, arXiv) to constrain non-Gaussianity in the isotropic connected 4-point correlation functions of BOSS.

In the data/ directory, we provide:

• Isotropic 2PCF, 3PCF and full/disconnected 4PCF measurements from BOSS in the CMASS-NGC and CMASS-SGC regions.
• Full/disconnected 4PCF measurements from 1000 MultiDark-Patchy mocks in the CMASS-NGC and CMASS-SGC regions.
• Analytic covariance matrices for the NGC and SGC regions, derived assuming Gaussianity, isotropy and a uniform survey geometry in Hou et al. (2021, arXiv).

All data are computed using the encore code of Philcox et al. 2021a. The main analysis is done in the Jupyter Notebook.
