Here are astrophysical data sets for extra-dimension analysis.
AstroXX.tar.gz contain following files:

- SZMap.ICA.Filter.NoBack.fits:
	this is a 2d array of the recovered map from which sources are extracted.

- Catalog.Contaminant.txt & Catalog.Contaminant.fits:
	this catalog (in ASCII or fits format) contain sources that are identified as 
	galaxy clusters. This is the signal we look for in the map.
	
- Catalog.Cluster.txt & Catalog.Cluster.fits:
	this catalog (in ASCII and fits format) contain sources that are contaminants 
	(radio point sources). This is the signal we DON'T want.

Each AstroXX.tar.gz file contain a different map and corresponding catalogs.
Some sets could be used to train a neural network or SVM algorithm
and the other to test it on unknow data (I have more if needed).

Catalogs format is given in the header of ASCII catalogs (.txt).
Here is a more detailed description:
Col0  (Flux)    is the flux of the source
Col1  (Flux0)   is the central pixel value
Col2  (Radius)  is the recovered radius of the source (in pixels)
Col3  (FWHM)    is another estimation of the size of the source (in pixels), 
				does not work sometime, use Radius instead
Col4  (Ell)     is the ellipticity of the source
Col5  (Elo)     is the elongation of the source = 1-1/Ellipticity
Col6  (Var)     is the variance of the pixel distribution of a small submap supposed to contain the source
Col7  (Skew)    is its skewness (of the pixels of the small submap supposed to contain the source)
Col8  (Kurt)    is its kurtosis (of the pixels of the small submap supposed to contain the source)
Col9  (Conc)    is the concentration = Flux/Flux0 (or Flux0/Flux ??)
Col10 (XPos)    is the X (NAXIS1 in fits header) position of the source (in pixels)
Col11 (YPos)    is the Y (NAXIS2) position of the source (in pixels)
