! History:
! Jul 2007 - A. Bodas-Salcedo - Initial version
! Oct 2008 - S. Bony          - Instructions "Call for large-scale cloud" removed  -> sgx%frac_out is used instead.
!                               Call lidar_simulator changed (lsca, gbx%cca and depol removed; 
!                               frac_out changed in sgx%frac_out)
! Jun 2011 - G. Cesana        - Added betaperp_tot argument
