      FILTER_SAD is a module which can filter SAD files by various
 built-in and user-defined filters.

 FILTER_SAD, Version 3
 Open the file to be filtered
 Enter the filename:  (<CR> for default)
 FILE=
 OUT
 There is one map in the file
 Reading from the file
  155 rows of  155 pixels in R4 format
 Define the area to be filtered
 Enter start-column end-column start-row end-row:  (default = entire map)
 BOUNDARIES= 
          1
 BOUNDARIES=
          1
        155
          1
        155
 Enter the name of the file to be written to:
 FILE=OUT
 Writing to an existing file
 There is one map in the file
  155 rows of  155 pixels in R4 format
 Enter the output map number:  (default = 1 after last map)
 MAPS_OUT=2
 Enter the starting location in the output file for the lower left corner
 of the filtered area in the input file:  (default = input file location)
 STARTING_LOCATION=
          1
          1
 Enter a choice for the unfiltered region in the output file:
          C = Copies it from the input file (default)
          L = Leaves it in its original state
          Z = Zeroes it

 CHOICE=Z
 Enter the filter type:
             B  = Box average (default)
             BM = Box median
             BR = Bas relief
             G  = Gaussian
             H1 = High pass or edge enhancement
             H2 = High pass or edge enhancement
             H3 = High pass or edge enhancement
             H4 = High pass or edge enhancement
             H5 = High pass or edge enhancement
             M  = Unsharp mask
             UB = User defined box
             US = User created SAD file
 Note that user defined functions are self-normalizing
 when the DC term is included

 FILTER_TYPE=G
 Enter the amplitude (ADU) and the sigma (pixels):

 PARAMETERS=10 6
 Enter the ellipse inclination angle:  (default = 0.0 degrees)
 INCLINATION=
  0.000000E+00
 Enter the eccentricity of the ellipse:  (default = 0.0)
 ECCENTRICITY=
  0.000000E+00
 Enter the baseline (negative value gives a lowered gaussian):  (default = 0.0)
 BASELINE=
  0.000000E+00
 Do you wish to exclude edited areas (zero value):  (default = N)
 EXCLUDE=
 F
 File extended to map   2
