Data from the Back Wide-Field Camera
Stellar Objects in this image
Note: positive radial velocities indicated objects moving away from us. Blue flux is measured at 440nm, green at 500nm, and red at 700nm. Units are:
| Measurement | Unit |
|---|---|
| Position | degrees |
| Flux | W/nm/m2 |
| Parallax | arcsec |
| Radial Velocity | km/s |
| Variable | unitless (=1 if variable, =0 if not) |
Uncertainties in this data (one standard deviation figures) are:
| Measurement | Uncertainty |
|---|---|
| Flux | 1% |
| Position | 0.0001 degrees |
| Parallax | 0.001 arcseconds |
| Radial Velocity | 0.03km/s |
