ROTATE/1DIM in out nop_flag
	rotate a 1-dim profile around its startpoint
\us\pu
Purpose:     
           Rotate a 1dim profile around its startpoint.
\up\sy
Syntax:      
           ROTATE/1DIM in out [nop_flag]
\ys\pa
           in = 1-dim input frame
\ap\pa
           out = 2-dim output frame
\ap\pa
           nop_flag = optional number-of-pixel flag;
\\
               ODD - no. of pixels in x- and y-direction of output frame will
                     be: 2*input_nopix - 1
\\   
               EVEN - no. of pixels will be: 2*input_nopix;
\\ 
               defaulted to ODD

Note:        
           This command should be helpful if you need to create pointspread
           functions or filters. Just define the cross-section and then use
           this rotation.
\\
           Pixels outside the original domain of the 1-dim frame, i.e. the
           pixels in the corners of the 2-dim result frame, will be set to the
           value in the keyword NULL.

Examples:
\ex
           ROTATE/1DIM profile psf
            Rotate 1-dim frame `profile.bdf' and create 2-dim frame `psf.bdf'
            with the ODD option.
