VizieR Online Data Catalog: Radial velocity study of π Mensae (Hatzes+, 2022)

Our radial velocity (RVel) data consist of archival and new measurements from our ESO's HARPS large follow-up program. A total of 77 RVel measurements come from the UCLES spectrograph mounted on the 3.9m telescope of the Anglo Australian Telescope (AAT). Archival HARPS data consisting of 145 RVel measurements (51 nightly averaged) were also taken from the public archive of the European Southern Observatory (ESO). We also included 275 RVel measurements (37 nightly averaged) taken with the ESPRESSO spectrograph.

The new data for π Men were taken as part of our ESO observing programs 0101.C-0829, 1102.C-0923, and 106.21TJ.001 (PI: Gandolfi) and during technical nights (program IDs 60.A-9700 and 60.A-9709) on HARPS. These consisted of 413 RV measurements 27 spanning 2018 September to 2020 December. Exposure times were 150-300s, resulting in a median S/N of ~250/pixel at 550nm.
