Make lighter skewer files by ignoring cells at z < z_skewer_cut #22

Closed andreufont closed 4 years ago

andreufont commented 6 years ago

Very often, when generating Lyman alpha mocks we don't need to store information below z=1.9 or so, but we are storing skewers with cells going all the way to z=0. It would be great to have an option (z_skewer_cut or similar), that could be set to the minimum redshift you'd like to store.

Note that some times you might actually want to store all the information to z=0. For instance we might at some point be interested in cross-correlations of metals lines with low-z quasars, or things like that, but this would be an special case. I'd say that the default for z_skewer_cut should be set to 1.9.

@andreufont : sorry for my delay, been a bit offline for the last few weeks. I'll get on this and #21 ASAP.

andreufont commented 6 years ago

@damonge No worries at all, we are still testing code and playing around. This will only be critical once we start mass production of mocks.

We already had multiple mass production runs and we never had a problem with disk space, so I'm closing this
