J/A+AS/112/125 Lightcurves of minor planets (Hainaut-Rouelle+, 1995)
================================================================================
Lightcurves of selected minor planets
Hainaut-Rouelle M.-C., Hainaut O.R., Detal A.
<Astron. Astrophys. Suppl. Ser. 112, 125 (1995)>
=1995A&AS..112..125H (SIMBAD/NED BibCode)
================================================================================
ADC_Keywords: Minor planets ; Photometry, UBV
Keywords: asteroids
Description:
We present 81 photometric lightcurve of 36 minor planets observed in
the V and B bands at the ESO 50cm telescope at La Silla (Chile).
These asteroids were selected preferentially in order to improve their
ecliptic longitude coverage in view of pole determinations and lightcurve
inversions. We also give some first photometric observations and/or
rotational period for several asteroids.

Note (1): For 423 Diotima, 3 solutions of Pnew are found, cf text
Note (2): 'P' indicates that a pole orientation was published, and
'R' that the pole orientation is highly accurate and reliable
Note (3): the groups are numbered
0 = no complete lightcurve have been published yet
1 = complete lightcurves are available for one distinct opposition
2 = complete lightcurves are available for 2 distinct oppositions
3 = complete lightcurves are available for 3 distinct oppositions
4 = more than 3 distinct oppositions and pole determination has
been performed
