Principle of the Program

1. Creates a 1D image containing the continuum and possible emission lines.
2. Induces absorption features on this image.
3. Possibly, comparison of the resulting image with observations. According to the result, the user can then modify some of the input parameters and repeat the operation until the agreement is found to be satisfactory.

The package contains:

 
4 commands: 		  CREATE/PSF 		 : 		 creation of the instrumental response

           		  COMPUTE/EMI 		 : 		 computation of the initial unabsorbed
                                                    spectrum

     		  COMPUTE/ABS 		 : 		 main program, computation of the theoretical

                         		  		 		        absorption spectrum.

     		  TUTORIAL/CLOUD 		 : 		 on line tutorial

3 tables: 		  EMI     		 : 		 contains the emission line parameters

          		  ABSP    		 : 		 contains the atomic data

          		  ABSC    		 : 		 contains the absorption line parameters

                            		 		  		                (cloud model)

4 keywords 		  CLDDIM 		 :)

           		  CLDZ   		 :) 		 monitor several parameters or options

           		  CLDCT  		 :) 		 common to the 3 commands

           		  CLDOP  		 :)
