VizieR Online Data Catalog: GIARPS T Tauri spectra (GHOsT) (Gangi+, 2022)

Observations were carried out from October 2017 to January 2020. They consist of high-resolution optical and IR spectra obtained with the GIARPS instrument that were flux-calibrated through ancillary low-resolution spectroscopy and photometric data.

GIARPS observations. The sample was observed in four distinct runs, hereafter run I in October - November 2017, run II in December 2018, run III in November 2019 - January 2020, and run IV in October - December 2020. The GIARPS observing mode consists in the simultaneous use of the HARPS-N (resolving power R=115000) and GIANO-B (R=50000) spectrographs. HARPSN is a fiber-fed echelle with a FoV=1" and covers the spectral range between 390 and 690nm while GIANO-B is a nearinfrared cross-dispersed echelle with a slit on-sky with dimensions of 6"x0.5" and a spectral range between 940 and 2400nm.

To accurately flux-calibrate the GIARPS spectra we carried out contemporaneous ancillary observations consisting of absolute flux-calibrated low-resolution spectroscopy and photometry. In particular we acquired optical low-resolution spectra (R=2400, 330-790nm) with the 1.22m telescope of the University of Padova at the Asiago observatory (Italy). Spectra were reduced and flux-calibrated against spectrophotometric standards flux zeropoint with BVRcIc photometry acquired with the ANS Collaboration telescopes in runs I-III, while in run IV, griz photometry was taken with the ROS2 instrument of the REM telescope. In the NIR we obtained JHK photometry that was acquired in run I, II, III-2019 with the REMIR instrument at the REM telescope and in run III-2020 and IV with the NICS camera at the TNG telescope. In addition, we also acquired low-resolution (R~50) NIR spectra in run IV using the NICS Amici prism.
