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.

USNO-A :
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).
