nc_xcor_ssc_sij_set_area (
NcXcorSSCSij* ssc_sij,

)
Description [src]
Selects the crude finite-area estimator, $S_{ij} = S^{\rm fullsky}{ij} /
f{\rm sky}$ with $f_{\rm sky} = \Omega / 4\pi$: the full-sky matrix simply
rescaled by the sky fraction area subtends. This is not a mask
deconvolution, and it knows nothing about the shape of the footprint; use
nc_xcor_ssc_sij_set_mask_cl() when the shape matters.
It is kept because it is what an analysis quoting only a survey area uses, and because it costs a single multipole rather than the whole $\ell$ range a mask needs.
Setting a positive area discards any mask spectrum, the two being mutually
exclusive; passing 0.0 restores the plain full-sky matrix.
