Parallax Systematics and Photocenter Motions of Benchmark Eclipsing Binaries in Gaia EDR3

Previous analyses of various standard candles observed by the Gaia satellite have reported statistically significant systematics in the parallaxes that have improved from ∼250 μ as in the first data release (DR1) to 50–80 μ as in the second data release (DR2). Here we examine the parallaxes newly re...
