Tempo 11.000 Installation

• Create a directory (e.g. tempo11) and cd to it.
  
  
• Download the following files from ATNF (Australia) or Princeton (USA):
  
  

  • tempo11.tar.gz:     ATNF Princeton

  • DE200.1950.2000.gz: ATNF Princeton

  • DE405.1950.2000.gz: ATNF Princeton

  • TDB.1950.2050.gz:   ATNF Princeton

  
  Note: these are large files. It may be easier to use anonymous-ftp directly to download the files rather than downloading them via a web browser.
  
  
• Uncompress the ephemeris files. It is recommended that these be moved to to a parallel directory, e.g. tempo_ephem.
  

  gunzip DE200.1950.2050.gz DE405.1950.2050.gz TDB1950.2050.gz
  mkdir ../tempo_ephem
  mv *2050 ../tempo_ephem
  
  

• Un-compress the source files:
  

   gunzip tempo11.tar.gz 

• Un-tar the source code and support files:
  

   tar -xf tempo11.tar

• This creates several subdirectories, including `src' which contains the source code. Go to this directory:
  

   cd src

• Compile the code. The executable will be `tempo11/tpo'

   make tpo

• Go to the tempo11 directory:

   cd ..

• Set environment variable TEMPO to point to the tempo11 directory using the full path name. For example, using csh in the directory `/disk1':

   setenv TEMPO /disk1/tempo11

• Edit tempo.cfg. Change the CLKDIR and EPHDIR entries to the full path of the tempo11 directory, including a slash after the path. Change PARDIR to the full path of the tempo11/tzpar subdirectory. Change OBSYS to the full path of the file tempo11/obsys.dat. For example, if the root directory is `/disk1', these entries in tempo.cfg would be

  CLKDIR     /disk1/tempo11/
  PARDIR     /disk1/tempo11/tzpar/
  EPHDIR     /disk1/tempo_ephem/
  OBSYS      /disk1/tempo11/obsys.dat   
  	  

• Make a backup copy of `tempo.lis' from the distribution:

   cp tempo.lis tempo.lis.original

• Run tempo on a test file:

   tpo 0437.tim

• Compare the tpo output file with the file from the distribution:

   diff tempo.lis tempo.lis.original

  Ideally only two lines of these files will differ--the line with the tempo execution time, and the line with the input file name (with its full path). There may be more differences in some systems (especially those not using IEEE arithmetic) due to roundoff errors, etc.
