PICO Sparse focal plane simulation of noise
Software versions
Configuration
All 21 bands
pixels/wafer reduced to 7 for all bands
sampling frequency reduced all to 63 Hz, unless it was already lower
hitmaps and noise covariance matrices corrected to be representative of the full focal plane and nominal sampling frequency
baseline 1/f and white noise
1 year
output units of all products are `microKelvin_CMB`
-
Results location
Available maps:
IQU maps binned and destriped with Madam
White noise covariance matrices `wcov.fits`, white noise levels were reduced in order to be representative of the total focalplane
Original hitmaps from Madam (less detectors, lower sampling rate) and corrected hitmaps representative of nominal focal plane

Validation
Consistency check of hitmaps, noise covariance matrices, NET and TT spectra of the noise maps:
Comparison of a 30 days simulation of the sparse and the full focalplane for band 9:
There is a difference in the dipoles, but the level is tiny.
I checked the dipole in map domain, the sparse map has 14e-3 muK, while the full focalplane map as 7e-3 muK. I checked also the 1 year simulation and that has 6e-3 muK.
