General installation:

1. Create a new P3d directory, let's call it <P3d-path>
2. Copy the file P3d.tar from the P3d-CD ROM to <P3d-path>
3.  Unpack the P3d-software with the following commands:

     cd <P3d-path>
     tar -xvf P3d.tar
     rm P3d.tar
 

Personel access to P3d:

Once the software is installed it has to be initialized for every user.
To do so add the following lines in exactly the given order to your idl-startup-file  startup.pro:

   defsysv,'!p3d_path',<P3d-path>
   !path=!p3d_path+':'+!path
   .run p3d_init

<P3d-path> stands for the string giving the full path name of the upper level P3d directory.
If you don't have a personel startup.pro file then create a new one containing at least the lines written above, put it into your <IDL directory> and add the following command to your .cshrc or .login file:

   setenv IDL_STARTUP <IDL directory>/startup.pro
 

Getting started:

After having started IDL print:

   p3d_online

this will start the P3d-online reduction interface. To proceed individual reduction procedures without using the interface see the Module Reference.
