Support SACC output format

7

LSST DESC is planning to use SACC files for passing around two-point data. Would be nice to have TreeCorr output to this format natively. cf. https://github.com/LSSTDESC/sacc

Feature request: correlation of vector quantities

4

It is currently possible to use TreeCorr to compute the correlation functions of a scalar quantity (using kappa as proxy) as well as the shear, defined through g1 and g2....

Computing NN correlation from simulated catalogues without a random catalogue

5

I've been using `treecorr` to compute the halo-halo correlation function from haloes identified in an N-body simulation. I am working in periodic 3D, with x, y and z positions of...

I've been thinking for a while it would be useful to have a metacal catalog class in Treecorr that would provided a standard/well-tested piece of code for calculating and applying...

TwoD Binning in Rperp metric.

1

Hi, I have implemented a code that compute projected clustering (NG correlation for intrinsic alignments wg+(rp), NN correlation for wgg(rp)), with the Rperp metric. Since TwoD binning is only valid...

Outlier point in NN Correlation

3

Hello, When I measure the angular two-point correlation function, I sometimes have an outlier point with a much lower amplitude and when it happens, it is systematically in the first...
