Notes. The exposure time corresponds to one exposure. The S/N is per pixel and per exposure at 1.7 μm. The barycentric Julian date is shifted by −2 450 000. SPIRou hasbeen used in both polarimetric and spectroscopic modes (“Pol” and “Sp”). Zero-point (ZP) indicates the mean CFHT/SKYPROBE extinction during the visit, when available, in magnitude (Cuillandre et al. 2016). The last two columns “RV phn” and “RV rms” show the average photon noise of the sequence and the scatter observed at a given epoch over the N data points when the planet signal is removed, respectively.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
