Table 4

Pre-launch predicted radial velocity precision for the specified stellar types in Table 1 for end of mission.

Spectrum Magnitude Dead Mode RV precision
V band time (km s−1)
B1V 7 0.14 HR 0.6
G2V 13 0.34 LR 0.6
K1III MP 13.5 0.34 LR 0.6

B1V 12 0.34 LR 8.5
G2V 16.5 0.42 LR 12.8
K1III MP 17 0.42 LR 13.3

Notes.The precision does not include calibration residuals. Dead time combines the likelihood of all of the effects in Sect. 8.8. From Fusero & Chassat (2011).
