We report the discovery of 
visual double
stars, mostly with separations between 0.3 and 1 arcsec,
from a dedicated re–reduction of the Tycho data from the
star mapper of the ESA Hipparcos satellite.
The new doubles are combined with
WDS systems identified in the Catalogue, and 1220 new
doubles, to form
the Tycho Double Star Catalogue, TDSC, a catalogue of absolute astrometry
and BT, VT photometry
for 
components of 
double and multiple star systems.
We also include results for 
single components for systems
unresolved in TDSC, and a supplement gives Hipparcos and
data for 4777 additional components.
The TDSC thus contains a total of 
entries.
Cross identifications are given to WDS, HD, Hipparcos and .
Key words: stars: binaries: visual / catalogs / astrometry
