Abstract:
This catalog contains the observational results obtained by the
Celescope Experiment during the first 16 months of operation of NASA's
Orbiting Astronomical Observatory (OAO-2). Magnitudes were obtained
from more than 8000 television images in UV.
Description:
The Orbiting Astronomical Observatory (OAO-2) containing the Celescope
Experiment was launched 7 December 1968.

Note (1): Spectral peculiarities are coded on 8 bytes, from left to right:
1: 'P' indicates a peculiar spectrum
2: 'E' indicates any type of emission
3: 'N' stands for Nebulous lines, 'S' for Sharp lines
4: 'A' indicates a peculiar A-type star
5: 'M' indicates a metallic-line star
6: 'S' indicates a shell spectrum
7: 'U' indicates a source observed in the UV below 300nm
I: 'S' indicates a standard in the MK or UBV system
Note (2): Celescope magnitudes are based on spectral irradiance in SI
units: Un=-2.5logI, where I is the spectral irradiance (in units
of watts per square meter per meter of wavelength: W/m2/m) from
the observed star.
Note (3): Pecularities of the source is coded on 3 bytes, from left to right:
1: stellar multiplicity:
'V' for Visual binary,
'S' for Spectroscopic binary,
'E' for Eclipsing binary,
'C' for Composite spectrum,
'M' for multiple star;
2: nebulosity:
'E' for Emission nebula,
'O' for Object surrounded by or associated with nebulosity
3: 'G' for Galactic cluster
Note (4): the variability types are:
A = α CVn type
B = β CMa type
C = Classical Cepheid (δ Cep)
G = Eclipsing variable
H = Suspected variable
I = Irregular variable other than Ia (coded 'X')
L = RR Lyr variable
N = Nova-like
P = peculiar variable
V = TV Tau variable
X = Early-type irregular variable (type Ia)
Y = Unspecified variable
Note (5): this code specifies which magnitudes are given as mag1 mag2 mag3:
1: V, (B-V), (U-B);
2: V, (B-V);
3: V;
4: mv, ppg;
5: ---, pmg;
6: mv;
11: V, (B-V), (U-B)c (Cape);
17: V, mpg, (U-B);
19: mv, (B-V), (U-B);
21: mv, (B-V), (U-B)c;
28: mv, (B-V);
36: V, (B-V), (U-V);
