CONVERT/ECHELLE input output domain function param option
	resample echelle orders
\us\pu
Purpose:    
            Resample echelle orders. The command is used internally by
            RESPONSE/ECHELLE and REPEAT/ECHELLE to convert the instrument 
            response from high to low resolution and vice versa.

Syntax:     
            CONVERT/ECHELLE input output domain function param option
\ys\pa
            input     = input file with the echelle orders
                        (wavelength-order format)
\ap\pa
            output    = resampled output file
\ap\pa
            reference = defines the output sampling domain as
                        - two real numbers: start,step
                        - a filename used as reference
\ap\pa
            function    = rebinning function
                        (LIN,POL,INV,EXP,DEX,LOG,DLG,IPO,U01)
\ap\pa
            param     = parameter related to the conversion method
                        (for LIN, default is 0.,1.)
\ap\pa
            option    = rebinning method.
