dwhan89 commented 5 years ago

Here is an extension of default SignalGen class that generate Sehgal CMB and FG signals (noise parts are not changed)

Swapping out act baseline cmb and fg sims with Sehgal 09 sims with following modifications

  1. CIB and TSZ maps are scaled by 0.75 following Section 2.4.1 of https://arxiv.org/abs/1808.07445
  2. 15mJy cuts are applied to CIB and Radio point sources. Sources are identified at 150GHz
  3. FG include CIB, TSZ, KSZ, Radio

Pre-rotated Sehgal (CMB&FG) sims are also available. You can pass eulers= (psi, theta, phi) parameters when initializing Sehgal09Gen object to access them.

ex) s09gen = simgen.Sehgal09Gen(version=version, eulers=(0,theta,0)
