Create or collect mocks for mass mapping validations #5

Open mdschneider opened 7 years ago

mdschneider commented 7 years ago

To validate mass mapping algorithms, we want to run on lensing mocks as a 'truth' comparison. We need to get available mocks from the collaboration and/or create our own (approximate) mocks.

@damonge @j-dr Could you describe here the format of your mocks ? like size, depth, availability of a true convergence map, this kind of thing ?

EiffL commented 7 years ago

I have opened branch #5 to implement the code for automatically generating mocks following the HSC footprint as well as the true convergence map from different simulations. I'm writing a generic empty interface for now, that we will fill-in with the code we are developing today.

On NERSC we have:

The raw Mira-Titan mocks are here: /project/projectdirs/lsst/desc-wl/wl-massmap/mira-titan/ and a version with simplistic shape noise added: /project/projectdirs/lsst/desc-wl/wl-massmap/mira-titan/v1

The Buzzard mocks are here: /lsst/jderose/BCC/Chinchilla/Herd/Chinchilla-0/addgalspostprocess/truth

Just merged scripts to generate mock shape catalog from any simulation wrapped in the DESCQA framework, for now that includes Joachim's Mira-Titan sim, Buzzard and some Proto-DC2 catalog. @mdschneider does that resolve the issue ?
