Description:
    UBV photometry  of 955 galactic  foreground stars in  the direction to
    the Large  Magellanic Cloud is  presented. The stars  have been chosen
    from  foreground star catalogues and have  been measured to complete a
    new data base containing entries  of  more  than  5000  stars  in  the
    direction of  the LMC. First and  second order extinction coefficients
    at La Silla/Chile  are given,  which differ  from the  standard values
    because of the 1991 eruption of the volcano Mt. Pinatubo.

Note (1): the acronyms are:
     A  = Ardeberg (1972)
     S  = Fehrenbach & Duflot (1970) supplement, uncertain membership
    RV = Feast et al. (1960)
    HV = Harvard Variable No., Leavitt (1908)
Note (2): Stars referenced by their P number in Fehrenbach & Duflot (1970):
      385 Variable HV 5509
      450 Wrong Hodge & Wright number given by Fehrenbach & Duflot (1970):
          not 29/94 but 29/95
      486 Double star (dist. approx. 4''; both components only measured
           in common
      663 Variable HV 5650
      827 Variable HV 2435
     1013 Double star (dist. approx. 2"); both components only measured
           in common; HDE 269526 is listed as FD 1013 and FD 1014 by
           Fehrenbach & Duflot (1970): components of binary (?)
     1045 U-B has been measured only twice
     1054 Close binary (Feast et al. 1960: dist. = 1"), both components
           only measured in common
     1190 Star lies at the edge of a nebula
     1253 Identification as HDE 269939 by Fehrenbach & Duflot (1970) is
          correct; HDE is numbered twice (cf. FD 1259)
     1259 Identification as HDE 269939 by Fehrenbach & Duflot (1970) is not
           correct
     1356 Variable HV 6024
     1641 Wrong Hodge & Wright number given by Fehrenbach & Duflot (1970):
           not 61/64 but 61/60
     1646 Wrong Hodge & Wright number given by Fehrenbach & Duflot (1970):
           not 61/60 but 61/64
     2003 Double star ?
  HD36705 Short period variable with a period of approx. 12 hours,
           amplitude in V = 0.09 mag; measurements were obtained on
           November 29, 1991
