Product description

A general description of the product, including e.g. figures related to the contents (e.g. maps, tables), and some explanation of its scientific meaning. If there are scientific warnings about the use of the product (User’s caveats), they should also be given here, or at least references to other explanatory documents (papers etc).

Auto and cross angular power spectra for the 13 detset maps available at 100, 143 and 217GHz are provided in the Planck Legacy Archive with the following file structure: to be written by A. Moneti

They were obtained by Spice with the so-called Galactic mask2 apodized to 2degrees, and point sources mask apodized at 30arcmin combining the sources detected by HFI(Planck) High Frequency Instrument at any frequency between 100 and 353GHz with the SZSunyaev-Zel'dovich and ERCSCEarly Release Compact Source Catalog sources catalog.

The spectra, computed up to ell=3508, are corrected from the effect of the cut sky, and from the nominal beam window function and average pixel function. (Spice reference)

The covariance matrix only describes the statistical correlation induced by the sample variance and cut sky, using the formalism described in Efstathiou 2004, also sketched in the appendix of P08 paper (likelihood), assuming the instrumental noise to be white and uniform.

Production process

Description of the Pipeline used to generate the product. In particular any limitations and approximations used in the data processing should be listed. Avoiding detailed descriptions of methods and referring to other parts of the ES and/or the relevant Planck papers for the details. References however should be quite detailed (i.e. it is not enough to direct the user to a paper, but the relevant section in the paper should be provided).

Inputs

A list (and brief description to the extent possible) of the input data used to generate this product (down to file names), as well as any external ancillary data sets which were used.

Related products

A description of other products that are related and share some commonalities with the product being described here. E.g. if the description is of a generic product (e.g. frequency maps), all the products falling into that type should be listed and referenced.
