>From the rebinned quasi 2-D spectra, individual orders can be extracted in individual files or all orders can be merged in a single 1-D spectrum. In the latter case, the spectra are averaged in the overlapping regions. The edges of the orders containing too little signal have to be removed before the averaging. This is especially important for FEROS, since the blue orders are much shorter than the CCD. A table with the limits of the orders is supplied for FEROS spectra. The corresponding command is MERGE/FEROS.
