Query: New phase-magnitude curves for some Main Belt asteroids, fit of
  different photometric systems and calibration of the albedo - photometry
  relation   Results of photometric observations of a small sample of selected Main Belt
asteroids are presented. The obtained measurements can be used to achieve a
better calibration of the asteroid photometric system $(H, G_1, G_2)$ adopted
by the IAU, and to make comparisons with best-fit curves that can be obtained
using different photometric systems. The new data have been obtained as a first
feasibility study of a more extensive project planned for the future, aimed at
obtaining a reliable calibration of possible relations between some parameters
characterizing the phase-magnitude curves and the geometric albedo of
asteroids. This has important potential applications to the analysis of
asteroid photometric data obtained by the Gaia space mission.
