Ci. Lagerkvist et al., PHYSICAL STUDIES OF ASTEROIDS .29. PHOTOMETRY AND ANALYSIS OF 27 ASTEROIDS, Astronomy & Astrophysics. Supplement series, 113(1), 1995, pp. 115-129
In this paper photometry and analysis of 27 asteroids are presented. F
or the asteroids 21 Lutetia, 23 Thalia, 250 Bettina and 135 Hertha spi
n vector determinations were made. For asteroid 99 Dike we derived a r
otation period of 10.35 hours and for 1280 Baillauda the period was fo
und to be 12.6 hours. For 23 Thalia, 66 Maja and 250 Bettina the slope
parameter was derived from the present data.
