PICO Sparse focal plane simulation of noise

• TOAST: `119db6ae8204230aafbaf0cb1d46d84f8d36cbf3`
• `pico-simulations`: Tag `201806_sparse_focal_plane_noise`

• 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`
• see the SLURM scripts and other configuration files

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

Consistency check of hitmaps, noise covariance matrices, NET and TT spectra of the noise maps:

• All bands (slow to load)
• Just band 10

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.
