GaiaDR2_binarySearch Files

In general, one can compile the C programs in this project with the cmpld
script.

NOTE: The file locations of both the original WDS and Gaia DR2 data and the
subsequent reformatted data reflect their location on my computer. You'll need
to change these locations to reflect where they are on your computer. You also
need to download, unpack, and incorporate the includeFiles.tgz into the #include
listings at the start of each program.

These programs will reformat the ASCII text of both the wds_precise.txt
and Gaia DR2 files into structures quickly accessed by subsequent programs:

For wds_precise.txt: preciseRfmt.c,
    Gaia DR2:        rvGaia2gBin.c

Once in the new format,

  getStatsFromWDSorbits.c: Finds the Gaia DR2 stars associated with binaries
  with computed orbits in the WDS.

  findCandidateStars.c: Searches the Gaia DR2 stars for stars with parallax,
  radial velocity, and proper motions with values greater than 3 times their
  listed errors.

  newBinariesInGaiaDR2.c: Searches the sorted Gaia list created by
  findCandidateStars.c for possible binaries based on their relative spatial
  velocities.

  analyzeBinaries.c: Searches the output from newBinariesInGaiaDR2.c for pairs
  that already exist in the WDS and WDSS. It then creates a commas separated
  variable format text file of those pairs not found.
