Preliminary Requirements

• PULSAR runs in an Open Windows environment.
• PULSAR references the following files

  1.

  $TIMING_DIR/psrtime.dat - Princeton pulsar parameter file.

  2.

  $TIMING_DIR/psrbin.dat - Princeton binary pulsar parameter file.

  3.

  $TIMING_DIR/leap.secs - Table of UTC leap seconds.

  4.

  $TIMING_DIR/ephem.gro - JPL Ephemeris file in IEEE format.

  5.

  $MISC_DIR/timeline - File of valid GRO observation periods.

  6.

  $ALT_PSRTIME - Alternate catalog of pulsars in Princeton format.

• If a Summary Database (SMDB) file will be processed, it must be in $SMDB_DIR.

where $TIMING_DIR, $MISC_DIR, $SELECT_DIR, $SMDB_DIR, and $ALT_PSRTIME are environmental variables with the names of appropriate directories or files.
