#
#			 	  Selection of the catalogue:
#			              F814W(auto)<24.5
#
#			          Total number of objects:
#			              237914
#
#				~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
#
#   i)   The catalogue contains morphological information for 237912 objects 
#	 in the ACS catalogue (Leauthaud et al. 2007, apjs, 172, 219)
# 
#   ii)  Morphological parametric quantities have been computed using Morpheus 2005
#        (Abraham , R.~G. et al. 2007, apj, 669, 184)
# 
#   iii) SExtractor (Bertin & Arnouts) is used in a hot/cold configuration to
#        optimimse the deblending
#   
#   iv)  Morphological types are estimated in three different ways.
#        Please do acknowledge the proper paper according to the classification you use:
#        - dist_int    --> Tasca et al. in preparation ; Cassata et al. in preparation
#        - class_linee --> Abraham, R.~G et al. (1996), mnras, 279, L47 ; Cassata et al. in preparation
#        - class_SVM   --> Huertas-Company, M., Rouan, D., Tasca, L., et al., 2008, A&A, 478, 971
# 
#   v)   The catalogue contains  237912 lines of data in 12 columns
# 
# 
#	 MORE IN DETAILS:
#	 ----------------
#	 The morphological study is performed on HST-ACS images 0.03"/pix.
#	 Particular attention has been put in the tuning of the SExtractor
#	 parameters used to produce segmentation images. 
#	 The reason is that Morpheus (Bob's code) computes morphological 
#	 measurements starting from SExtractor segmentation images. 
#	 It is therefore fundamental to reduce cases where galaxies are not deblended.  
#	 Since this morphological catalogue is HST-ACS selected we used the
#	 same hot/cold method as Leauthaud et al. (2007) in order to provide
#	 a one-one match with the official HST/ACS catalogue.
#	 
#	 To transform morphological parameters into morphological classes is
#	 not a trivial job.
#	 To help the user we provide three different morphological classification
#	 all obtained starting from structural parameters measured with Morpheus.
#	 Our preference is for the class named "dist_int". This method has already been
#	 used in Cassata et al. (2007) and optimised for this release. 
#	 The method is explained in Tasca et al. (in prep) and Cassata et al. (in prep).
#	 Another classification based on a support vector machine is the
#	 parameter named "class_SVM". We refer to Huertas-Company et al.(2008)
#	 for further details.
#	 The parameter "class_linee" is the morphological class obtained with an
#	 optimisation of the standard and widely used Abraham et al. (1996) technique 
#	 of subdividing the galaxy population into classes on the basis of 
#	 position on an asymmetry versus concentration diagram.
