CMB realizations lensed with gaussian potential

Tag: mbs-s0009-20191107

Released on 7 November 2019 by @zonca

100 CMB realizations for all channels from alms with best-fit Planck cosmology and gaussian lensing potential.

Input components

All maps are in uK_CMB, IQU, single precision (float32)

Instrument properties

Beams are read from sotodlib.

Available maps

HEALPix maps at high resolution (nside 4096) and low resolution (nside 512), so we have a set for each resolution for all channels. All maps are full-sky, see the 201906_noise_no_lowell release for hitmaps.

The ell_max for the harmonics transform is 3*Nside-1.

Location at NERSC:

/project/projectdirs/sobs/v4_sims/mbs/201911_lensed_cmb

The naming convention is:

{nside}/{content}/{num:04d}/simonsobs_{content}_uKCMB_{telescope}{band}_nside{nside}_{num:04d}.fits"

where:

• content is cmb
• num is from 0 to 99
• telescope is sa or la
• band is the channel band, the options are: LF1,LF2,MFF1,MFF2,MFS1,MFS2,UHF1,UHF2

Backed up to tape in ~zonca/sobs/mbs/201911_lensed_cmb.
