This archive contains the release of the Boomerang LDB power spectrum data published in deBernardis, et al., Nature, 404, p.955, (2000). ---------- The archive contains: File Columns Description 'Cl' [l,Cl,dCl] - band-power Cl in bands centered on l, with error dCl 'bin' [lmin,lmax] - min/max values of the multipole l in bands 'd2LdC2' [d2LdC2] - likelihood curvature matrix. Read-in format: do i=1,12 do j=1,12 read(*,*)d2LdC2(i,j) enddo enddo 'xb' [l,xb] - Shift of the lognormal distribution in bands centered at l. 'beam' [l,W(l)] - Window function values for l=0 to l=1024. File contains a 5-line header. ---------- Units: Cl, dCl, xb are in (micro-K)^2, d2LdC2 is in (micro-K)^(-4)
