Description:
Photoelectric magnitudes and colors in the Johnson-Morgan UBV system
for 477 stars in 6 square degrees near Kapteyn Selected Area 141
(l=245, b=-86; 00 43 < RA < 01 11, -33.7 < Dec < -26.9, B1950.0)
are given in the first data file. The estimated rms accuracies
are 0.02 (V), 0.03 (B-V), 0.07 (U-B) for stars in the magnitude
range 15 to 16. Table 2 of the source reference gives
the mean errors for intervals of magnitude.
Photographic V magnitudes and B-V colors are given for 2835 stars
to magnitude 17 (in the same region as above) in the second data
file. The estimated rms accuracies are 0.05 (V) and 0.08 (B-V). The
mean errors of the computed right ascensions and declinations are
0.15s and 2", respectively.

Note (1): J2000 position of the source, and comments, not in the original
table, were added in April 2016 from B. Skiff [Lowell Obs.].
The source of the position is given in the column "s" with the keys:
T = position from Tycho-2 (I/259)
U = position from UCAC2 (I/289) or UCAC4 (I/322)
M = position from 2MASS (II/246)

Historical notes:
The data were keypunched for Kavan U. Ratnatunga in 1982 June at
the data center of the Australian National University, Canberra.
They were supplied to the Astronomical Data Center/NASA Goddard
Space Flight Center by K. Ratnatunga in 1986 April.
Data format modified at the Astronomical Data Center (ADC)/NASA GSFC,
1991 October...Wayne H. Warren Jr.
A standardized "Intro" description file was added in March 1994 at CDS
(Joseph Florsch). Some errors were corrected: consecutive signs ± in
Table pe, col. U-B, line 215 (missing value)
Table pg, col. B-V, line 805 (29.3.096) (two consecutive signs ±)
Table pg, col. B-V, line 2637 (30.5.048) (two consecutive signs ±)
Changes made at ADC in Aeptember 1997 (N.P.M. Kuin, C.-H. Joseph Lyu) in
Table pe: changed in record 155, 268, 335 positions in RA with RAs=60
to RAm=RAm+1 and RAs=00.
Accurate positions of the stars, and comments about duplicity, were
added by Brian Skiff [Lowell Obs.] and forwarded to CDS in April 2016.
