The Gaia-LSST Synergy: This paper discuss the synergy of Gaia and the LSST. Gaia has a magnitude limit r=20, and LSST will extend these measurements to r=27.5. Gaia and LSST will deliver trigonometric parallax, proper-motion and photometric measurements with similar uncertainties. Gaia and LSST datasets will be highly complementary and synergistic. And users of Gaia data have developed data analysis skills required to benefit from LSST data.
properMotion.ipynb: In this notebook, I run the ProperMotionMetric, which calculate the uncertainty in the returned proper motion. I run this metric on the baseline and pontus opsim databases, results are shown inside.
Figure 2: Compare the astrometric uncertainty to the uncertainty that would result if half the observations were taken at the start and half at the end. A perfect survey will have a value close to 1, while a poorly scheduled survey will be close to 0.
