| DATA_SET_DESCRIPTION |
Data Set Overview : This collection of magnitude-phase relations of selected asteroids has been compiled from the published literature at Kharkiv University by V.G. Shevchenko and colleagues. It contains observations dating from 1978 through 2008. Mainly the observations were performed at the Institute of Astronomy (Kharkiv, Ukraine) and at the Astrophysics Institute (Dushanbe, Tadjikistan). For most asteroids the magnitude-phase relations were obtained down to phase angles less than 1 deg. For some asteroids the magnitudes are presented in three (UBV) or four (BVRI) standard spectral bands. It is planned to update this data set annually with additional observations. The magnitude-phase relations, along with observation date, ecliptic latitude and longitude, and heliocentric and geocentric distances, are included in the file magphase.tab. The published papers for the observations are listed in the file magphaseref.tab

| CONFIDENCE_LEVEL_NOTE |
Confidence Level Overview : The accuracy of the asteroid absolute photometry is determined by the uncertainties of the magnitudes for standard stars and relative photometry on the night of observation. Uncertainties of the magnitudes for relative photometry are +/- 0.005-0.020 mag for the different bands. The calibrations of the magnitudes were performed with standard star sequences from Landolt (+/-0.003-0.010 mag). We have obtained the following uncertainties on magnitudes for different bands: U : +/- 0.02 a 0.03 mag; B : +/- 0.015 a 0.025 mag V : +/- 0.01 a 0.02 mag; R : +/- 0.01 a 0.02 mag I : +/- 0.015 a 0.025 mag The upper limit can be taken for the confidence level. For additional information on the confidence level of the observations see the individual published papers, listed in the file magphaseref.tab.
