Evaluating the stability of atmospheric lines with HARPS
Astronomy and Astrophysics
Context: In the search for extrasolar systems by radial velocity technique, a precise wavelength calibration is necessary for high-precision measurements. The choice of the calibrator is a particularly important question in the infra-red domain, where the precision and exploits still fall behind the achievements of the optical. Aims: We investigate the long-term stability of atmospheric lines as a precise wavelength reference and analyze their sensitivity to different atmospheric and observingdoi:10.1051/0004-6361/201014005 fatcat:3kctkljjp5bjxcu6iib2rannka
