The CLASS noise simulations were generated using the Fourier domain noise model inferred during the mapmaking procedure; see Li et al. (2023). Random time domain realizations constrained to be consistent with the noise spectrum were then mapped to generate noise simulations appropriate for use in characterizing the mapped data.

There are 200 noise simulations for each of the three delivered map sets: the full CLASS 2016 - 2022 survey interval (coadd), the m1 base split (m1) and the m2 base split (m2). These have been packaged as three compressed tar files, one each for coadd, m1 and m2.
