SKY2000 - Master Star Catalog :
This the new name for the
"SKYMAP Star Catalog" by Myers J.R.,Goddard
Space Flight Center, Flight Dynamics Division. It as
nothing to do whit the Sky Catalog 2000 from Sky
Publishing.
Tycho Catalog :
Be careful when using this
data for astrometric purpose, the proper motion error are
sometime large.
Tycho Input Catalog :
This catalog is normally
obsolete as its main purpose is Tycho data reduction. But
from an amateur point of view it may be considered as a
subset of the GSC up to magnitude 12. It remain very
interesting for its compact size, homogenous limiting
magnitude and color indication in some fields.

Calibration catalog
:
A1.0 and SA1.0 : GSC
A2.0 and SA2.0 : ACT
North-South limit is -30°
for A1.0 and -20°/-18° for A2.0.
Stars colour do not represente b-v as other catalogues
but (mb-mr)*0.6
Performance : The
catalogue structure do not allow fast access to the data.
Effectively, the index file (.acc) define zone of 7.5°
in declination by 15' in right ascension, this is a very
large area for the catalogue scale. Each zone contain up
to 3'000'000 stars ( 10 time the SAO !) and can only
accept sequential access. So be patient and prefere the
GSC for navigation purpose then switch to USNO-A when you
are satisfied by all other parameters.

Notes :
N: Notes found in the Notes table.
O: Orbit. Where motion has exceeded 360 degrees, no
values are listed in the position angle and separation
columns. Orbits may be found in the "Fourth
Catalog of Orbits of Visual Binary Stars" (Worley
and Heintz, 1983), and in the Information Circulars
published by Commission 26 of the IAU, as well as
in the literature.
a: Pair appears in an appendix list, not part of the
discoverer's regular numbering system.
r: Pair was listed, but in a "rejected" list,
not part
of the discoverer's regular numbering sequence.
s: Pair has other discoverer's designations and numbers
in the literature due to duplicate discovery.
We have given credit to the earliest discovery
observation (and correct identification) reported
in the literature. The List of Synonyms follows the
List of Additional Discoverers.
p: Coordinates and proper motions from the ACRS, PPM,
IRS, and FK5 catalogs.

Lynds' Catalogue of Bright
Nebulae :
The following codes
are used for Color:
'1' if brighter on
blue Palomar plate;
'2' if equal on
red and blue Palomar plates;
'3' if brighter on
red Palomar plate;
'4' if visible
only on the red Palomar plate.
The brightness scale
varies from
'1' (brightest) to
'6' (barely
detectable).
