! This file contains the luminosity_total_tool and luminosity_labeled_tool
! modules before implementing the LUMINOSITY command.
!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!
! *** JP: This command requires double thinking before parallelize it!
!
! *** JP: It should be ported to subcube when the question of double cube access
! *** JP: will be sorted out
