The determination of asteroid <i>H</i> and <i>G</i> phase function parameters using <i>Gaia</i> DR2

The Gaia mission will provide the scientific community with high-quality observations of asteroids all categories. second release data (DR2) was published in 2018 and consisted 22 months 14,099 known Solar System objects, mainly asteroids. purpose this work is to obtain a catalogue phase function parameters (H G) for that are observed by mission, which were DR2. For purpose, we introduced an algorithm capable building from magnitude UTC epoch present DR2 database. Since never observe angle 0{\deg} (corresponding opposition), but angles higher than 10{\deg}, added ground small angles) thus improved determination $H$ $G$ function. In case, also build H, G1, G2 We compared our results G those Astorb database level agreement satisfactory.
