Discussion Overview

The discussion revolves around the output file generated by the CAMB code, specifically focusing on the columns of the TT power spectrum (C_l) contained within the output file. Participants seek clarification on the structure of the file and the specific location of C_{TT}(l).

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant inquires about the contents of each column in the CAMB output file, specifically asking for the location of C_{TT}(l).
  • Another participant responds that C_{TT}(l) is found in the first column after the column denoting the l's.
  • A later reply expresses satisfaction with the provided answer and offers further assistance regarding power spectrum estimation or analysis.

Areas of Agreement / Disagreement

Participants appear to agree on the location of C_{TT}(l) in the output file, as indicated by the response to the initial inquiry.

Contextual Notes

None noted.

Who May Find This Useful

Individuals working with CAMB output files, particularly those interested in power spectrum analysis in cosmology.

Hi, all!

The camb code is available at

http://lambda.gsfc.nasa.gov/toolbox/tb_camb_form.cfm

in a web interface form. One of it's output files, named something like

camb_13685314_scalcls.dat

should contain the scalar [tex]C(l)[/tex]'s.

Can anyone tell me, what exactly is contained in each column of that output file. Namely, in which column [tex]C_{TT}(l)[/tex] is contained?

Thanks in advance!
Angelos
