Power Spectrum
These two files (in ASCII and FITS versions) contain the Archeops power spectrum for each of 25 bins. The table contains 6 columns: l_min, l_max, l(l+1)C_l/2pi, total error, statistical error, cosmic variance.
Units are uK_CMB^2.

Covariance Matrix

These two files (in ASCII and FITS versions) contain the covariance matrix for the Archeops power spectrum (in uK^4). It is a 25x25 matrix describing the 25 bins of the released power spectrum.
The error bars for each bin can be computed from the square root of the diagonal of the covariance matrix.

and - November 2004.



Window Functions
These two files contain the window functions (in ASCII and FITS versions) for the Archeops power spectrum bins. The integral of the window functions are normalized to 1 for each of the 25 bins and are computed between l=0 and l=1000. The table contains a float array with dimension 25 x 1001 (25 columns by 1000 rows). The window functions are defined as follows (with implicit sum over repeated indices) :
(1)
In the MASTER framework [Hivon et al., 2002], if we define as :

(2)
Then the window function reads:

(3)
Where and are the binning and reciprocal operators.
Using this definition, we have for each bin:
