This file is a 3D fits image that contains the smoothened density map of the galaxy distribution as a function of binning of R.A., Dec and redshift. This quantity is obtained from the PAZWav detection code by convolving the galaxy distribution with a "mexican hat" wavelet  kernel function.
For each dimension this file contains the WCS keywords (CRPIX, CRVAL, CDELT, CTYPE, CUNIT), plus those used internally by the code to set the coordinates (NAME, NUMBER, START, CENTER, END, STEP). For this reason, there is redundancy in the information. The 3 axis shoud represent, respectively, the Right Ascension, the Declination and the Redshift. The complete list is as follows:

#. **DET_CODE**: an identifier of the cluster model used in the filtering procedure
#. **WCSAXES**: number of World Coordinate System axes
#. **CRPIX1**: WCS reference pixel for the first axis (Right ascension, zenithal/azimuthal equal area)
#. **CRVAL1**: WCS reference position for the first axis (Declination, zenithal/azimuthal equal area proj)
#. **CDELT1**: WCS step for the first axis
#. **CTYPE1**: the coordinate type for the first axis
#. **CUNIT1**: the coordinate unit for the first axis
#. **CRPIX2**: WCS reference pixel for the second axis
#. **CRVAL2**: WCS reference position for the second axis
#. **CDELT2**: WCS step for the second axis
#. **CTYPE2**: the coordinate type for the second axis (Declination, zenithal/azimuthal equal area proj)
#. **CUNIT2**: the coordinate unit for the second axis
#. **NAME_2**: name of the second axis
#. **CRPIX3**: WCS reference pixel for the third axis
#. **CRVAL3**: WCS reference position for the third axis 
#. **CDELT3**: WCS step for the third axis
#. **CTYPE3**: the coordinate type for the third axis (Redshift)
#. **CUNIT3**: the coordinate unit for the third axis
#. **LONPOLE**: Native longitude of celestial pole
#. **LATPOLE**: Native latitude of celestial pole
#. **RADESYS**: Equatorial coordinate system (ex: "ICRS")
