Changing Bins

After struggling with a segmentation fault problem, I have run the reconstruction with different bins. The 3D correlation functions seem to be having some problems at small separations (see plot below), need to look into this. The reconstruction still looks ok, although it seems to be very dependent on how many phi bins I use to reconstruct (see Playing with Reconstruction post). I need to get to the bottom of this. Next step, seeing what it looks like on the CAS data.

Playing with Reconstruction

First selection function:
sf=selection(0.2,0.1,0.05,0.2,bins)


First phi:
Best Reconstruction:
Other reconstructions (not so good):

New selection function:
sf=gals.selection(0,0.05,0.3,10,bins)

New phi:
Best reconstruction:
Other reconstructions:
