e2e-simulation

scripts folder:

• produce_det_names_files.ipynb: jupyter notebook for producing the files with the detector information needed for e2e_simulation.py. All and only the detectors in each file will be used by e2e_simulation.py.

• e2e_simulation.py: this script produces the official end-to-end simulations for the LiteBIRD collaboration. This code is meant to be used with files produced by produce_det_names_files.ipynb and each file should contain only detectors in one channel (see examples in the ancillary folder). If the simulation index is 0, TODs and maps are saved. If the simulation index is > 0, only maps are saved. The produced TODs are cmb, foregrounds, white noise, 1/f in the pessimistic case (f_knee = 100 mhz), 1/f in the realistic case (f_knee = 30 mhz) and dipole. The TODs are saved for each day. The produced maps contain:

  • cmb, fg, 1/f noise for the pessimistic case
  • 1/f noise for the pessimistic case
  • cmb, fg, 1/f noise for the realistic case
  • 1/f noise for the realistic case
  • cmb, fg, white noise

• run_simulation.py: example script for running e2e_simulation.py in a HPC facility (the example is for NERSC). Before using it, fill the #COMPLETE HERE fields

• pos_vel.py: script for calculating the spacecraft position and velocity over time

ancillary folder: files with the detector information needed for e2e_simulation.py. All and only the detectors in each file will be used by e2e_simulation.py. Each file contains detector belonging to one channel
