VizieR Online Data Catalog: Near-infrared spectra for TW Hya (McLure+, 2020)

Catalog contains three fits files, each containing one epoch of near-infrared spectra for TW Hya. Epoch 1 and 2 are archival ESO VLT-Xshooter spectra that were downloaded from the ESO archive and corrected for telluric absorption with the MOLECFIT tool. Epoch 3 was observed with Magellan FIRE and corrected for telluric absorption with the standard FIREHose pipeline and a telluric standard star. All other information regarding these data can be found in Appendix A of the paper.

One spectrum of TW Hya was obtained with the FIRE spectrograph (Simcoe et al., 2013PASP..125..270S) at Las Campanas (R~6000, 0.8<λ<2.5um)(30) on January 2, 2013 (PI McClure). Two 6.0 second exposures in the Fowler 1 read mode were obtained with the 0.6" slit under 0.45" seeing at an airmass of 1.009 in excellent conditions. We obtained the usual suite of arc lamp and flat-field calibrations and extracted the FIRE spectrum using the standard FIREhose pipeline, with MCN 7202 as the telluric calibrator star. The other two spectra were obtained with VLT X-shooter (Vernet et al., 2011A&A...536A.105V) (visible: 0.8-1um, R~18000; near-IR arm: 1-2.5um, R~11000) on April 7, 2010 and May 3, 2010. We corrected ESO's Phase 3 reduced data for telluric absorption using the MolecFit software package. Spectra from all three epochs were corrected for their heliocentric velocities, and the X-Shooter spectra were convolved down to the resolution of the FIRE spectrum.
