III/135 THE HENRY DRAPER CATALOGUE (edition 1989)
================================================================================
CANNON A.J., PICKERING E.C.: 1918-1925
Ann. Harvard College Obs. 91-100
================================================================================

Description:
See the attached file "adc.doc" by Nancy G. Roman and Wayne H. Warren Jr.
The following few modifications have been added at CDS (October 1993):
(a) insertion of the decimal point for Ptm and Ptg fields
(b) three stars had a declination "-6859" corrected to "-6900":
269534, 269975, 270350
(c) a 0 digit missing in the DEm field of stars
16110 16112 16126 16131 16138 16150 16156 16183 16187 16189
has been added
(d) the spectrum of star 4815 has been corrected

Historical Notes:
* 16-Apr-1994: Following a note by Sh. Nishimura (NAO Japan),
about 60 remarks E and P (emission and peculiar) where changed to
lowercase letters. BD designation of star 237694 have been changed
from BD+567 1286 to BD+56 1286.

1- 6 I6 --- HD [1/272150]+ Henry Draper Catalog (HD) number
7- 18 A12 --- DM Durchmusterung identification:
Bytes 7-8: catalog ID, 'BD', 'CD', 'CP', or
'AG' for AGK1 stars (zones +50 to +59)
not in the BD
Bytes 9-16: Durchmusterung catalog number,
SZZNNNNN. For AG zones, the ZZ field
contains the lowest declination zone
in the appropriate catalog (50 or 55)
Byte 17: BD supplement letter
