Fix Version/s: None
Create a package for treecorr to allow for calculation of correlation functions in a fast, robust, and tested code.
This will not add dependencies to lsst_apps or lsst_distrib.
Implementation is likely
1. Create wrapper install packages for treecorr.
2. Figure out how to avoid adding the FITS reader dependency in treecorr.
3. Add treecorr dependence to validate_drp table file.
TreeCorr is a "[c]ode for efficiently computing 2-point and 3-point correlation functions" and is being proposed for use in validate_drp to calculate the correlation function of the PSF residual ellipticity (
DM-8951). The GitHub repo is here:
TreeCorr depends on the following Python packages.
