; NAME:
; dustem_set_data
; PURPOSE:
; Initializes the dustem data structure (!dustem_data)
; CATEGORY:
; Dustem
; CALLING SEQUENCE:
; dustem_set_data(data_sed=data_sed,data_ext=data_ext,[/help])
; INPUTS:
; spec: array of structures containing a SED
; OPTIONAL INPUT PARAMETERS:
; None
; OUTPUTS:
; None
; OPTIONAL OUTPUT PARAMETERS:
; None
; ACCEPTED KEY-WORDS:
; help = If set print this help
; COMMON BLOCKS:
; None
; SIDE EFFECTS:
; initializes !dustem_data
; wavelengths are forced to be the central filter wavelength for
; photometric data
; RESTRICTIONS:
; The dustem idl wrapper must be installed
; PROCEDURE:
; None
; EXAMPLES
; dustem_init
; dir=getenv('DUSTEM_SOFT_DIR')+'/src/dustem3.8_web/SEDs/'
; file=dir+'Gal_composite_spectrum.xcat'
; spec=read_xcat(file,/silent)
; dustem_set_data,spec
; MODIFICATION HISTORY:
; Written by J.-Ph. Bernard
; see evolution details on the dustem cvs maintained at CESR
; Contact J.-Ph. Bernard (Jean-Philippe.Bernard@cesr.fr) in case of problems.
;
; V. Guillet (2012) : dustem_set_data is turned into a function which can be used
; indifferently for sed, ext, polext
; I. Choubani (2022): Introducing the dustem_check_data procedure where the new format outlined by the latest release is taken into account.
; This function uses two main input structures: DATA_SED and DATA_EXT. Polarization data is included within each.
