Extended Data Table 2 Measured values of positions and radial velocities

From: A population of dust-enshrouded objects orbiting the Galactic black hole

  1. Data are shown for G3, G4, G5 and G6. The epochs are reported as modified Julian date (MJD). The positions (RA and dec.) are offsets from Sgr A* in arcseconds. The position uncertainties are the standard deviation obtained through a Monte Carlo method. The radial velocities (RV) are in km s−1 and have been corrected for the local standard of reference (LSR). The reported radial velocity uncertainties (err.) are purely statistical (1σ of the line fit). There is an additional systematic uncertainty that we fold into the orbit fit.
