Description:
The catalog is a compilation of photoelectric photometry obtained as
part of a program investigating the distribution of stars and stellar
matter perpendicular to the galactic plane. Compared to the
publication, the "catalog" file does not include the position, the
spectral type, the source of the UBV photometry, and neither the
number of measurements in the narrow-band filters.
The observations have mainly been made with the 33cm photographic
tube of the Uppsaala double refractor, using a diaphragm of 0.7mm
corresponding to 33". A small number of measurements have also been
made with the 15cm Zeiss-Heyde astrograph. The observations were made
between January 1967 and April 1968.

9- 13 F5.2 mag Vmag ? Visual magnitude in Johnson system
15- 20 F6.3 mag B-V ? Colour in Johnson system
22- 26 F5.2 mag U-B ? Colour in Johnson system
28- 33 F6.3 mag m(4508) Magnitude in narrow-band filter (1)
35- 39 F5.3 mag ge = m(4269) - m(4508) (1)
41- 46 F6.3 mag ce = m(4176) - m(4269) (1)
48- 50 A3 --- Rem [V?DR ] Remark (2)
52- 54 I3 --- Seq [1/629] Sequential number
--------------------------------------------------------------------------------
Note (1): The narrow-band filters are:
---------------------------------------------------------
m(4508) centered at 450.8nm, half-width=5.0nm
m(4269) centered at 426.9nm, half-width=4.3nm
m(4176) centered at 417.6nm, half-width=4.0nm
---------------------------------------------------------
ge = m(4269) - m(4508) measures the break at the G-band
ce = m(4176) - m(4269) measures the CN absorption.
---------------------------------------------------------
Note (2): remarks are:
V = variable;
D = double star, magnitude difference less than 4mag
R = individual remarks:
* HR 1457 : The individual values of Vmag indicate variability
* HR 1845 : CE Tau
* HR 2742 : BZ Cam
* HR 4057/8: The individual values of Vmag indicate variability
* HR 5490 : W Boo
* HR 5505/6: Spectral type A2V+K0II-II
* HR 5512 : The 3 measurements of m(4508) have an amplitude of 0.4mag
* HR 5589 : RR UMi
* HR 6406/7: Spectral type M5II + (G5III?+F2?)
* HR 7157 : R Lyr
* HR 7735 : V695 Cyg
* HR 7956 : T Cyg
* HR 8383 : VV Cep
