      EDITDATA1 is a module which edits data in a character file of type 1,
 the type produced by options EA and PR.  One can perform one of several 
 different mathematical operations on one or more columns simultaneously.

 EDITDATA1, Version 1
 Enter a command:
      A =  Adds a number to the data (default)
      M =  Multiplies the data by a number
      C =  Converts ADU to magnitudes
      D =  Converts magnitudes to ADU
      L =  Takes the logarithm
      G =  Adds a gradient to the data
      I =  Reintegrates the surface brightness
      R =  Multiplies by a gradient, keeping the average value the same
      B =  Smooths the data by binning
      B1 = Bins with the bin size equal to a constant times the radius
      B2 = Bins with the bin size equal to a constant times the radius squared
      B4 = Bins with the bin size equal to a constant times the radius
           to the fourth power
      S =  Subtracts two data files (first - second)
      T =  Adds two data files
      V =  Combines data from two files by averaging over their common region
           after incrementing one of them to match the other
      W =  Writes the positions, etc. to a file of type 2
  
 COMMAND=T		    ....Here we will simply add together some of the
				parameters of two different files.  These
				are stars which will be combined into a 
				point spread function.
 Open the first data file
 Enter the file name:  (default = last entry)
 FILE_21=S019134
 Enter the ID of the first file's object:  (default = last entry)
 ID=H
 Open the second data file
 Enter the file name:  (default = last entry)
 FILE_22=COPY		    ....We can't open the same file again, so a
				copy was made previously
 Enter the ID of the second file's object:  (default = last entry)
 ID=216
 Add the results to an existing file?  (default = N)
 OLD=
 F
 Enter the file name:  (default = last entry)
 FILE_23=TWO_STARS
 Enter one or more choices:
      C = Edits the column
      R = Edits the row
      I = Edits the inclination (default)
      E = Edits the eccentricity
      D = Edits the radius
      S = Edits the surface brightness
      L = Edits the log(integrated surface  brightness)
  
 CHOICES=I E S

 Enter the numbers to be multiplied:  (defaults = 1.0)
 NUMBERS=.5 .5 .5		    ....Notice that the numbers must be
					entered individually for each column.
					In general this gives more flexibility.
