Fr.: exactitude, précision
1) The state or quality of being → accurate.
From L. accuratus "prepared with care, exact," p.p. of accurare "take care of," from ad- "to" + curare "take care of."
Rašmandi, from rašmand, from raš + adjective forming suffix -mand.

High Accuracy Radial velocity Planet Searcher (HARPS)
A high-precision echelle spectrograph built for exoplanet findings and installed on the ESO's 3.6m telescope at La Silla Observatory in Chile. The first light was achieved in February 2003. HARPS has discovered dozens of exoplanets, making it the most successful planet finder behind the Kepler space observatory. HARPS can detect movements as small as 0.97 m s-1 (3.5 km h-1), with an effective precision of the order of 30 cm s-1, and a → resolving power of 120,000 (Mayor et al., 2003, ESO Messengar 114, 20).
→ high; → accuracy; → radial; → velocity; → planet; → search; → -er.
Fr.: imprécision, inexactitude
The quality or condition of being inaccurate.

Fr.: précision du pointage de télescope
