Background galaxy catalogs should be able to bin themselves #68

Closed sweverett closed 8 years ago

sweverett commented 9 years ago

It could be useful for a BackgroundCatalog to be able to plot a map of itself with the average value of different quantities (ellipticity, shear, convergence, etc) plotted as a colormap over an inputted bin-size. This method should also be able to bin the Kappamaps and Shearmaps in the same way for direct comparison.

Also visualizing cosmological density fields is the thing that will make us all famous.

Good point, forgot the most important part.

Switched this issue to you @drphilmarshall. Have fun making mass maps!

drphilmarshall commented 9 years ago

Will do! :-)

PS. I am working on demos/LensByHalos.nb, so best keep off that notebook for now to avoid conflicts. Thanks!

While more features could be added at a later time, background catalogs can now bin their convergence and shear values into corresponding kappamaps and shearmaps with a desired binsize. The lensing values binned can be from either lens_by_maps() or lens_by_halos(). Saving the figure directly to data/binned_maps is an option. Here are two examples, the first from lensed=map and the second from `lensed=halo': Map: kappa_map Halo: kappa_halo
