As prep for building MIT/SCSK
Curl 2-D path star charts, I have stripped the
hygxyz.cvs file to 100K rows for the stars North of -50 Dec. Please excuse my northern hemisphere bias.
I have made these CVS HipparcosYale+ files avail at
http://www.aule-browser.com/astro/stars/hygxyz_northofminus50.csv with alternates in three parts as hygxyz_PART_1_northofSouth50.csv and hygxyz_PART_2_northofSouth50.csv
etc.
For UTF-8 versions of any of these files, add
_ucs before the
.cvs extension.
Please let me know if you see issues.
The regex used to drop rows was:
^[0-9]+,[0-9]+,([0-9]+,|,)([0-9]+,|,)([A-Za-z0-9\s^,]+,|,)([A-Za-z0-9\s^,]+,|,)[0-9]+\.[A-Za-z0-9^,]+,-[5-8][0-9][\.].*$
The CVS header is
StarID,HIP,HD,HR,Gliese,BayerFlamsteed,ProperName,RA,Dec,Distance,PMRA,PMDec,RV,Mag,AbsMag,Spectrum,ColorIndex,X,Y,Z,VX,VY,VZ
