Product Download Page	Description	No. of Files/Size
Power Spectrum and All Supporting Data	The full VSA data set as a single tar file. Includes the following individual files.	1 file 164 KB
Root File with Power Spectrum	VSAF.dataset - a self-explanatory root file containing a header and the angular power spectrum to l=1400. There is no beam uncertainty for VSA data and the overall calibration uncertainty is 3%. After the header, there are 16 data points corresponding to the peak of the power spectrum likelihood.	1 file 858 B
X-Factors	VSAF_x.dat - the x-factors for the VSA data set (as explained in astro-ph/9808264, for example).	1 file 224 B
Hessian Matrix	VSAF_mat.dat - the Hessian matrix of the VSA data set in the log-offset variables. 16^2=256 numbers are given. Because the matrix is symmetric, the order does not matter. More...	1 file 1.7 KB
Windows Functions - Individual	VSAF* - 16 files with the window functions corresponding to each band power measurement. Each window file has two columns, the l value and the corresponding weight.	16 Files ~10 KB each
Windows Functions - Tar File	The 16 individual windows functions as a tar file.	1 file 153 KB
