Abstract:
    Photoelectric UBV photometry is presented for over 400 HD stars which
    lie within about a degree of selected cataclysmic variables. The data
    will be combined with polarimetry to determine the distances of the
    CVs.

Note (1): HD 89945  : Variable. Observed range in V∼0.28mag; 5 observations.
          HD 112343 : Identification uncertain. The fainter star (V=10.166) is
                       presumably the correct star (HD type G5) and the
                       brighter star is probably CD -29 10021.
          HD 116997 : Possibly variable. Observed range in (U-B)∼0.1mag;
                       2 observations.
          HD 118257 : Possibly variable. Observed range in V∼0.05mag;
                       2 observations.
          HD 154001 : Possibly variable. Single observation in 1991 different by
                       0.1mag from mean of 4 observations in 1992.
          HD 154882 : Pobably variable. Observed range in V∼0.1mag;
                       4 observations.
          HD 154936 : Pobably variable. Observed range in V∼0.09mag;
                       6 observations.
          HD 165761 : Variable. Observed range in V∼0.18mag; 4 observations.
          HD 174107 : = V603Aql ! Two observations with mean V=11.44 are clearly
                       of the CV itself. The two observations at V=9.95 are
                       presumably of the wrong object although there is no star
                       of such brightness within several arc minutes of
                       V603 Aql (Duerbeck, 1987SSRv...45....1D, p. 163)
          HD 186669 : Probably variable. Observed range in V∼0.09mag;
                       2 observations. Listed as V3960 Sgr in the General
                       Catalogue of Variable Stars (Kholopov et al., 1990,
                       Cat. II/139) Type LB (M5/7)
          HD 197010 : Variable. Observed range in V∼0.13mag; 7 observations.
          HD 197042 : Variable. Observed range in V∼0.13mag; 7 observations.
          HD 216482 : Close pair. The brighter star is presumably HD 216482
                       (=BD -3 5524) and the fainter star is then BD -3 5525.
