IHW Astrometry Network Data - Version 2                                       
This data set contains the revised version of the IHW Astronmetry             
Discipline collected data on comet 1P/Halley (1682 Q1).  In includes          
all the modern observations that contributed to the various orbital           
solutions produced during the International Halley Watch campaing.            
In addition, it also includes tables of re-reduced observations of            
1P/Halley during its 1835 and 1910 apparitions.  These data were              
produced by re-reducing the original observations using modern                
star catalogs (and re-scanned photographic plates, where available).
