Description:
The Compiled Catalogue (CC) is a photometric and astrometric survey
with the center at (RA, DE)_J2000 = (3.86h, 34.6{deg}) and radius of
10 degrees of a nearby region of star formation including the Per OB2
association. The CC is based on recently published astronomical
catalogues, e.g. Hipparcos and Tycho-2, and supplemented by relevant
astrophysical data from numerous data sources. The CC is complete down
to V=11.6mag, in general, and to V=18.5mag in the one square degree
field with the IC 348 cluster. The coordinates and proper motions are
reduced to the Hipparcos system and the photometry in the Johnson
system. Typical accuracies of 1-20mas for coordinates, 1-3mas/yr for
proper motions, 0.01-0.05mag for BV magnitudes were achieved for
majority of 29452 CC stars (V<12mag). For a large number of stars we
also collected parallaxes and spectral classes (about 7000 stars), the
R (about 2000 stars), I, J, H, K (about 500 stars) magnitudes, radial
velocities (330 stars). Stars in the Compiled Catalogue are sorted in
right ascension order.

Note on RAhr, DEdeg:
Epoch 1991.25, if the proper motions are available
Note on BD:
BD = Zone*100000 + running number within this Zone
Substituted with 0 if no data
Note on var1:
Byte 292 from Tycho-1 file tyc_main.dat, Cat. <I/239>
This flag is set when the variability is known:
G : variable known in General Catalog of Variable Stars
N : variable known in New Suspected Variables catalog
Substituted with blank if no data
Note on var2:
Byte 294 from Tycho-1 file tyc_main.dat, Cat. <I/239>
This flag has the following meaning:
U : apparent variability in the Tycho data; may be due to duplicity
V : strong evidence of intrinsic variability
W : suspected intrinsic variability
Substituted with blank if no data
Note on var3:
Byte 322 from Hipparcos file hip_main.dat, Cat. <I/239>
Hipparcos-defined type of variability (a blank entry
signifies that the entry could not be classified as variable or constant):
C : no variability detected ("constant")
D : duplicity-induced variability
M : possibly micro-variable (amplitude < 0.03mag)
P : periodic variable
R : V-I colour index was revised due to variability analysis
U : unsolved variable which does not fall in the other categories
Substituted with blank if no data
Note on var4:
Flag from CMC11 catalogue, Cat. <I/256>
V : variable star
Y or I : if the CAMC did not measure the mag, an approximate value
from other sources is given to a precision of 0.1 mag
X or R : star fainter than 12 with unknown mag is given as 12.
Substituted with blank if no data
Note on dup1:
Byte 202 from Tycho-2 file catalog.dat, Cat. <I/259>
blank : normal treatment, close stars were subtracted when possible
D : double star treatment. Two stars were found. The companion
is normally included as a separate Tycho-2 entry, but may
have been rejected
P : photocentre treatment, close stars were not subtracted.
This special treatment was applied to known or suspected
doubles which were not successfully (or reliably) resolved
in the Tycho-2 double star processing
Substituted with blank if no data
Note on dup2:
Byte 296 from Tycho-1 file tyc_main.dat, Cat. <I/239>
Unresolved duplicity status from Tycho data analysis:
D : duplicity clearly indicated (B_Tmag and V_Tmag refer to
combined light)
R : duplicity weakly indicated, combined with indication of
variability
S : duplicity suspected
Y : investigation for duplicity carried out on Tycho data,
no indication of duplicity was found
Z : investigation for duplicity not carried out
blank : Hipparcos star not observed by Tycho
Substituted with blank if no data
Note on dup3:
Byte 347 from Hipparcos file hip_main.dat, Cat. <I/239>
Indicates that further details are given in the Hipparcos Double
and Multiple Systems Annex:
C : solutions for the components
G : acceleration or higher order terms
O : orbital solutions
V : variability-induced movers (apparent motion arises from
variability)
X : stochastic solution (probably astrometric binaries with short
period)
Substituted with blank if no data
Note on dup4:
Flag from PPM-N catalog, Cat. <I/146>
Substituted with blank if no data
