CodeFromWDSvsUCAC5 Files

This "tarball" contains the entire WDS precise catalog and UCAC5, thus its 4.1GB
size. It will allow the user to recreate all of the calculations used to
determine the conclusions in the paper "Counter-check of 4,937 WDS objects for
being Physical Double Stars" by Knapp and Bryant, with the exception of the
spreadsheet calculation that determined if a given pair were optical or not.

The C code that did these calculations can be easily compiled on a computer that
has the gcc compiler installed on it. 

First, download the UCAC5vsWDScode.tgz file into a directory where you wish to
run it.  

From a command line terminal, cd to that directory and enter these commands:

gzip -d UCAC5vsWDScode.tgz

tar -xf UCAC5vsWDScode.tar

cd src

./compileThisCode.sh

./mkU5sd

./fvnp

./mu5w

./ckS

cd ../results

The results directory will contain these files:

WDSvsUCAC5.tab: This file is a tab delimited text file designed to be imported
into a spreadsheet. It contains all 4,937 pairs that had UCAC5 counterparts,
along with the WDS and UCAC5 data about those pairs.

PrimaryCompanions5arcSec.tab: Another tab delimited text file. It contains lists
of UCAC5 stars within 5" of a WDS primary.

ckSecondaryResult: A text file containing data from the ckS run.


Note: The results obtained by this software differ slightly from those in the
paper as the WDS precise catalog is from late September 2017, and those in the
paper were from the August 2017 edition of the catalog.
