Sample delta field to get galaxy positions and masses #1

Open dkirkby opened 9 years ago

dkirkby commented 9 years ago

Input is either numpy arrays or HDF5 file. Work from delta field at z=0 or light-cone physical density field?

I did the very first and dirty version:

github.com/slosar/fastcat

It uses randomfield to generate objects and sticks them into a Catalog object. Can also create randoms. See test/test.py there. rmags and currently random with a Gaussian distribution. It works in flat sky approx. No shears yet.

Galaxy correlations should be tested directly using treecorr to see if what we do makes sense...
