photemplate

     This program creates a PVL template to be used in photometry-based
     applications (such as photomet). There are two types of correction that 
     can be specified by this program:
  
      1) Photometric
      2) Atmospheric
      
     Photometric correction applies to the surface of an image. Atmospheric 
     correction applies to the atmosphere through which an image was acquired. 

     This program will allow the user to provide a FROMPVL file that has some
     preset parameters for different photometric and atmospheric models. Each
     planet has different surface and atmospheric properties that require model
     specifications that won't be applicable to other planets. It is important
     to set up the models and their parameters that apply to the planetary data
     you are working with.

     Example output files: 
      Example 1:

      Object = PhotometricModel 
       Group = Algorithm
          PhtName = Lambert
        EndGroup
      EndObject
      
      Example 2:
