RESPONSE/FILTER  std  [flux]  [resp]
 
16
        Generate a response image by filtering based method.
 
17
\us\pu
 
18
Purpose:    
 
19
            Compares an observed standard star spectrum to a reference 
 
20
            flux table and smooths the resulting response by filtering

Syntax:     
 
23
            RESPONSE/FILTER   std  [flux]  [resp]
 
24
\ys\pa
 
25
            std    = one-dimensional reduced spectrum of a standard star.
 
26
\ap\pa
 
27
            flux   = Flux table of the standard star. A collection of
 
28
                     flux tables is available in MID_FLUX. \\
 
29
                     Session keyword: FLUXTAB; no default value
 
30
\ap\pa
 
31
            resp   = Output response image.

Note:       
 
39
            1) The command applies in sequence a median and a smooth filter
 
40
            to the ratio image. The parameters of the filters are 
 
41
            respectively controlled by the session keywords FILTMED and
 
42
            FILTSMO.
 
43
 
 
44
            2) Broad absorption lines in the spectrum of the standard
 
45
            star tend to be propagated to the response curve. In this case
 
46
            the commands INTEGRATE/LINE and RESPONSE/LINE should
 
47
            preferably be used.
