IF somebody from RSI gets this, you should retrieve the file and include tvim
in your distribution, it is a much improved tvscl  the other routines are
useful too.

The following IDL procedures  were written at ESRG, UCSB, and are available
via anonymous ftp at esrg.ucsb.edu in /pub/idl/esrg_idl.tar.Z 

MVE   		Produces mean,min,max,standard Dev. and size of a given var

COLOR_PAL       Displays Color palette in separate window on screen

GLOBE_IMAGE	Maps an image to a globe, then rotates the globe.

TVIM                 A fancier version of TVSCL which allows               
                     for easy plot resizing, axis labeling and overploting,
                     and includes options for colored number scales.
                     This routine is used directly in TV_POLAR, and should
                     be used in conjunction with TRACE, GEN_COASTLINE and
                     COASTLINE.

STEP_CT              Discreetizes color scale at given numerical intervals.
                     This routine is used by PUT_COLOR_SCALE.

PUT_COLOR_SCALE      Draws a numbered color scale. This routine is used by
                     TVIM. 

TRACE                An interactive graphics procedure to find             
                     the set of array indecies which correspond            
                     to a user defined path. This routine is used by 
                     GEN_COASTLINE.
                                                                           
TV_POLAR             Display an image array defined in polar coordinates
                     (without resorting IDL's mapping routines). 
                                                                  
GEN_COASTLINE        Interactive graphic procedure used to generate        
                     coastal outline map used in COASTLINE.
                                                                  
COASTLINE            Superimpose coastal outlines over an image drawn 
                     with TVIM.
                                                                  
LOCATE               Given the coordinate arrays x(i,j) and y(i,j), LOCATE
                     finds the indices i0,j0 such the point (x(i0,j0),y(i0,j0))
                     is closest to a given point (x0,y0).  This routine
                     is used by COASTLINE.

SUPERPIX             Compute super pixel average and standard deviation    
                     of a scene.                                            

histo:  produces the histogram or cumulative histogram of an array 
            in number or in percentage of the total number of values
            selected in the array.

hilight: this procedure
            - select values according to a user defined criterion,
            - flashes the selected values,
            - display the histogram of the selected values.

            The criterion can be applied on the values of the input array
            or driven by an another array. for instance:
               1) locate in the array tab1, the values between 10 and 20.
               2) locate in the array tab1, the values where tab2 is between 
                     10 and 20.
