I/206         Bright Stars Supplement to PPM (Bastian+ 1993)
================================================================================
The Bright Stars Supplement to the PPM and PPM South Catalogue, Revised Edition
    Bastian U., Roeser S.
   <Astronomisches Rechen-Institut, Heidelberg (1993)>
================================================================================
ADC_Keywords: Positional data ; Proper motions

Description:
   A number of bright stars is missing from the PPM Star Catalogue, both
   on the northern <I/146> and on the southern <I/193> hemisphere. The
   Bright Stars Supplement described here makes PPM complete down to
   V=7.5 mag. For this purpose it lists all missing stars brighter than
   V=7.6 mag that we could find in published star lists. Their total
   number is 275. Only 2 of them are brighter than V=3.5. This replaces
   the December 1992 edition (catalogue I/194) of the Bright Stars
   Supplement which inadvertently contained 46 duplicates of stars
   already contained in the main parts of PPM.

Acknowledgement:
    The original ReadMe was prepared by Joseph Florsch of the CDS and 
    modified by Gail Schneider of the ADC. The version of the catalog
    that this described omitted the DM and SAO numbers, although there
    were spaces left for them.  These were inserted by Wayne H. Warren,
    Jr, We thank Dr. Warren for forwarding his improved version to us.
    The original version also had several columns that were copied from
    the basic PPM catalog that did not contain useful information in this
    version.  These have now been removed.
