Creation of CMB powerspectrum using CAMB

1. pars.set_cosmology(H0=67.74,ombh2=0.022,mnu=0.0,omk=0,tau=0.06,)
2. pars.InitPower.set_params(As=2e-9, ns=0.965, r=0)
3. pars.set_for_lmax(9000, lens_potential_accuracy=0)

Creation of CMB flat sky map using Healpy

1. project curved full sky CMB map to flat 20x20 deg^2 map

Creation of ISW-RS map

1. on-the-fly ray tracing simulations in range z=[0., 6.]

Creation of final sky map

1. unlensed CMB map + ISW-RS map

Transverse velocity measurement

1. apply gaussian smoothing filter of fwhm = 1 arcmin on full DeltaT map
2. apply gaussian high pass filter of fwhm = 5 arcmin on full DeltaT and alpha map
3. apply DGD3 filter on a cropped DeltaT and alpha map extending 30xR200 from halo centre
4. apodize using Hann window
