Purpose:      Select objects and store the positions in the intermediate table
\up\sy                                                                          
Syntax:       SELECT/ROMAFOT frame [int_tab] [wnd_size]
\ys\pa                                                                          
              frame =     input image frame
\ap\pa                                                                          
              int_tab =   name of intermediate table that will contain the 
                          selected objects; default is the frame name with
                          extension `INT'.
\ap\pa                                                                          
              wnd_size =  size of the area over objects will be fitted
                          (see FIT/ROMAFOT); default is 21 pixels both in the 
                          x and y direction (21,21)
\ap\pa
              name,mag,col1,col2 = interactive inquiry.\\
                           identification of the select object, the magnitude,
                           and two colours; \\
                           default nnn,0.0,0.0,0.0
\ap\no                             
Note:         The selection of the objects from the displayed frame is done
              with the cursor. For that purpose use the left cursor and 
              select each. Thereafter one is asked for the object name and its 
              colors. These parameters are necessary in case of objects to be 
              used as photometric standards, this command, in fact, stores three 
              {\it magnitudes} in the intermediate table. If this is not the case, 
              the default values can be used.

              After the selection procedure the intermediate table will contain
              a set of subarrays with dimensions according to the specified 
              fit window. The subframes are centered on the position of the 
              objects selected by the display cursor. Also, the table will 
              contain try values for the sky background and the central can be 
              passed directly to FIT/ROMAFOT.

              SELECT/ROMAFOT GCLUST ? 30,30
              Select the object from frame GCLUST and stores the data into 
              the intermediate table GCLUSTINT with array size of 30 by 30 
              pixels.
\xe\ex
              SELECT/ROMAFOT GCLUST INTTBL 20,20
              Select the object from frame GCLUST and stores the data into the
              intermediate table INTTBL with array size of 20 by 20 pixels.
