Abstract:
Photometric data on the Johnson BV system are given for 947 stars in a
field close to the bar of the Large Magellanic Cloud. The data have
been determined from electronographs calibrated through photoelectric
photometry. The visual magnitudes of the programme stars range from
V=14.63 to V=23.13.

Note (1): Stars Nos. 90, 721, 751 and 835 have the following
photoelectrically measured magnitudes:
--------------------
No. V B-V
--------------------
90 16.63 1.74
721 15.25 0.62
751 13.56 0.72
835 17.35 1.40
--------------------
Note (3): An * marks that the magnitude has been measured at an unusual
intensity, in most cases lower than normal.
Note (4): 5 denotes a perfect fit with no noticeable residuals
and 1 a fit estimated as unsatisfactory.
