ADCADC/CDS Standard Document for Catalog:
/external/nonstell/E7006/

The ADC has expanded its resources in order to better serve our users, we have developed a new category called "external" to complement our catalogs and journal table directories. You can access the data set described here through the URL:
http://www-obs.univ-lyon1.fr/hypercat.

The following is an abbreviated "ReadMe" document that describes this external data set.
E/VII/6   Hypercat Extragalactic Database                (Prugniel+ 1999)

Description:
   The purpose of Hypercat is to construct, maintain and interface catalogues 
   of galaxies useful for studying their physics. The data catalogued in 
   Hypercat complement those available through the other extragalactic 
   databases (NED and LEDA). Links to these databases and to ADS and SIMBAD 
   are provided for each object or reference.
   Hypercat is also developing data-mining procedures with the scope of 
   extracting astrophysical parameters from archived observations.

   Full mirrors of the database are available in other institutes.

   The main catalogues maintained in Hypercat are:
       Central velocity dispersion  <J/A+A/309/749> 
       Maximum velocity of rotation <J/A+A/309/749> 
       Line strength index Mg2 <J/A+AS/132/255>
       Aperture photometry <VII/206>
       Integrated photometry <VII/206>
       Spatially resolved kinematics  <J/A+AS/127/117>
       1&2-D kinematical data 
       FITS archive 

   Description of the FITS archive (HFA).
      The data presented in HFA are self-documented thanks to a consistent 
      set of keywords. These data may be downloaded as they are stored, or 
      they may be used to feed a customizable pipeline. The data finally 
      delivered can hence be fully calibrated (if desired), some further 
      reduction procedures (as subtracting the sky, extracting an object ...) 
      may also be applied. Basic measurements (kinematical profiles, 
      line strengths) may be performed along the pipeline. 
      The HFA has been open since January 1999. In June it contained about 
      35000 files.
