    Tool to find receiver tunings in order to prepare large frequency cover-
    age projects.

    The command argument is the Channel Spacing at  which  the  observations
    will  be  performed.  The correlator mode to be used will be defined ac-
    cordingly.

    With option /RANGE the command proposes a combination  of  tunings  that
    cover at least the specidified range. See help SPECSWEEP /RANGE.

    With  option  /NTUNING the users specifies the number of tuning he wants
    to use together with a frequency and an  alignement  code  in  order  to
    place the tunings

    The option /ZOOM can be used to select the frequency limits of the plot:
    whole receiver band or covered frequency range only.

    With the option /FILE name,  the  command  will  create  as  many  astro
    scripts   as  tunings  defined  by  the  command.  They  will  be  named
    name-[1-n].astro. They can be entered individually entered in  the  Pro-
    posal Management System to tranfer them into a proposal.

    With  the  option  /ADD_FEBE the created FrontEnd Backend configurations
    (FEBE) will be saved to the register. The commande  PROPOSAL  /FEBE  can
    then  be  used  to  create a PMS script for multi frequency observations
    (frequency cycling)
