; NAME:
; dustem_plugin_modify_dust_pol
; PURPOSE:
; Produces stokes emission parameters for the dust and synchrotron components
; CATEGORY:
; DUSTEM Wrapper
; CALLING SEQUENCE:
; dustem_create_stokes(st,key=key,val=val)
; INPUTS:
;
; OPTIONAL INPUT PARAMETERS:
; key = input parameter number
; val = input parameter value
; OUTPUTS:
; out = array containing the stokes emission parameters associated to the dust/synchrotron component or a concatenated version for both
; OPTIONAL OUTPUT PARAMETERS:
; None
; ACCEPTED KEY-WORDS:
; help = if set, print this help
; COMMON BLOCKS:
; None
; SIDE EFFECTS:
; None
; RESTRICTIONS:
; The dustem fortran code must be installed
; The dustem idl wrapper must be installed
; PROCEDURE:
; This is a dustem plugin
