What needs to be in the S&DA section of the CMB-S4 Science Book?

Julian:

For each mission phase (design, construction, deployment, observation):

  • What are the S&DA goals?
  • How do we ensure that progress is evolutionary, not revolutionary?


Simulations Flowchart

For each simulation element (sky simulation, data simulation):

  • What is the current status?
  • What is required in each mission phase?
  • What are the challenges to meet these requirements?


Data Analysis Flowchart

For each data analysis element (mission characterization, pre-processing, map-making, component separation, power spectrum estimation, parameter estimation, ... ):

  • What is the current status?
  • What is required in each mission phase?
  • What are the challenges to meet these requirements?


How do we collaborate on S&DA?

  • Standard data objects & formats
  • Pipelines & interfaces
  • Data distribution (take-out vs eat-in)
  • Synergies with S3, LiteBIRD, etc



Secondary anisotropies - lensing, tSZ, kSZ, CIB, cross-correlations, point sources, etc.

The roll that hydrodynamical simulations will play in focusing the science goals of S4 from secondaries

What are the simulation requirements for S4?

What do we have now?

Fast mocks
