# Archeops Data Products on LAMBDA

### CMB 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^2.

### CMB 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.

### CMB 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):

In the MASTER framework (Hivon et al., 2002), if we define
as

Then the window function reads:

Where
and
are the binning and reciprocal operators.

Using this definition, we have for each bin
:

### Dust Polarization Power Spectra

Dust polarized angular power spectra as measured by Archeops at 353 GHz for different galactic cuts (5, 10 and 20 deg). Tables contains : l_min, l_max, l(l+1)C_l^TT/(2 Pi) error, (l+1)C_l^TE/(2 Pi) error, (l+1)C_l^EE/(2 Pi) error, (l+1)C_l^BB/(2 Pi) error Units ARE microK_RJ^2.
