We describe here: GOG approach
The mean end-of-mission standard error for parallax includes: The mean end-of-mission standard error for parallax includes: all known instrumental effects 20 % margin (results from the on-ground data processing are not included)
Magnitudes: - G : broad-band (white-light), fluxes obtained in the astrometric instrument
- GBp and GRp: integrated from low resolution spectra
- GRVS: integrated from RVS spectrometer
Low-resolution spectro-photometry obtained in the Blue and Red Photometers - Spectral dispersion & wavelength range:
- BP: ~3 to ~27 nm pixel-1 ~330-680 nm
- RP: ~7 to ~15 nm pixel-1 ~640-1050 nm
- 1 CCD along scan each
RVS spectrometer: Resolving power ~11,500 wavelength range: 847-874 nm. 3 CCDs (strips) along scan
