Implement effective sky fraction functions #9

Open zonca opened 5 years ago

zonca commented 5 years ago

Implement functionality in mapsims to compute effective sky fractions for signal and noise dominated maps as defined below.

I would actually say that a more "standard" definition would be either fsky=< Nhits^2 >/< Nhits >^2 or fsky=< Nhits^2?>^2/ < Nhits >^4, which correspond to the effective number of modes for noise- and signal-dominated maps.

those are general enough, maybe add them to healpy instead
