CTRANS/ROMAFOT int_tab [tab_1] [tab_2] [pol_deg]
	find transformation of coordinates and apply to an intermediate table
\us\pu
Purpose:    Find transformation of coordinates and apply to a intermediate table
\up\sy
Syntax:     CTRANS/ROMAFOT int_tab [tab_1] [tab_2] [pol_deg] 
\ys\pa
            int_tab = intermediate table containing coordinates which must be
                      transformed from the system of tab_1 to that of tab_2.
                      No default.
\ap\pa
            tab_1   = table containing coordinates in the system to be 
                      transformed and created by the command CBASE/ROMAFOT.
                      The default name is TRACOO1.
\ap\pa
            tab_2   = table with coordinates in the system to transform to and 
                      created by the command CBASE/ROMAFOT. The default name is 
                      TRACOO1.
\ap\pa
            pol_deg = degree of polynomial to perform the transformation.
                      The rms of the two fits X=f(x,y) and Y=f(x,y)
                      is presented and the transformation is considered
                      satisfactory if the two rms are of the order of
                      a few tenths of pixel. Such transformation is usually
                      achieved with degree equal 0.
\ap\pa
            trans =   interactive inquiry.\\
                      Answer `Y' if the rms of the transformation is small
                      and, therefore, satisfactory. The command will then 
                      apply the transformation to the intermediate file.
                      Default is `N'.\\ 
\ap\no
Note:       Once the transformation is applied, the coordinates previously 
            stored the intermediate table are overwritten. The user is 
            therefore advised to save the intermediate table first by 
            making copy.

Examples:
\ex
            CTRANS/ROMAFOT GCLINT TAB1 TAB2 3
            Transform coordinates in the table GCLINT from the system in 
            TAB1 to the system in TAB2 using a polynomial of degree 3.
