; NAME:
; dustem_cc_print
; PURPOSE:
; Print out numerical values of color correction for a given spectrum in a given filter
; This is a sanity checking routine.
; Output should be compared to the color-correction tables published by different
; instrument teams.
; e.g. 1 MIPS HandBook, page 98
; http://irsa.ipac.caltech.edu/data/SPITZER/docs/mips/mipsinstrumenthandbook/MIPS_Instrument_Handbook.pdf
; http://irsa.ipac.caltech.edu/data/SPITZER/docs/mips/mipsinstrumenthandbook/51/
; AND
; e.g. 2 IRAS Explanatory Supplement, Table VI.C.6
; https://irsa.ipac.caltech.edu/IRASdocs/exp.sup/ch6/tabsupC6.html
; CATEGORY:
; DustEMWrap, Distributed, Low-Level, User convenience
; CALLING SEQUENCE:
; dustem_cc_print,filters[,restart=restart,help=help]
; INPUTS:
; filter: names of filters for which color correction will be printed
; OPTIONAL INPUT PARAMETERS:
; None
; OUTPUTS:
; OPTIONAL OUTPUT PARAMETERS:
; ACCEPTED KEY-WORDS:
; help = If set, print this help
; restart = If set, reinitialise DustEMWrap and use a new
; wavelength vector for integration.
; COMMON BLOCKS:
; None
; SIDE EFFECTS:
; None
; RESTRICTIONS:
; The DustEM fortran code must be installed
; The DustEMWrap IDL code must be installed
; If restart is not set, this routine should be called after the
; successful completion of a DustEMWrap run (i.e. without quitting the
; IDL session) since it will use existing system variables
; PROCEDURES AND SUBROUTINES USED:
; *** COMMENT AH --> is this really NONE? ****
; EXAMPLES
; dustem_print_cc,['MIRI1','MIRI6'],/restart
; dustem_print_cc,['IRAS1','IRAC2']
; MODIFICATION HISTORY:
; Written by JPB Apr-2011
; Evolution details on the DustEMWrap gitlab.
; See http://dustemwrap.irap.omp.eu/ for FAQ and help.
