Reduced IGRINS spectra: 2MASS J08173001-6155158

This Dataset contains the Gemini South/IGRINS spectra of the T6 dwarf 2MASS J08173001-6155158, and two Sonora Bobcat Alternative A models, as presented in Tannock et al. 2022a (submitted to MNRAS January 2022).

All files are text files. Header information is marked with a '#' at the start of the line.

There is one file for each IGRINS order in the H and K bands (see Table 2 in Tannock et al. 2022a for the wavelength coverage of each order), as well as an order-stitched file for each of the H and K bands. The data contained in each order is normalized to unity, and the stitched files are normalized to peak at unity.

The IGRINS data files have four columns:
column 1: vacuum wavelength in microns
column 2: flux in normalized F_lambda units
column 3: uncertainty on the flux
column 4: signal-to-noise ratio


The spectra are telluric corrected (we have divided the science spectrum by the spectrum of an A0V star), and are a weighted average of three epochs. These spectra DO NOT include the quadratic correction for instrument systematics described in Tannock et al. 2022.


The models are Sonora Bobcat Alternative A models generated by Callie Hood (Hood et al. in prep). These models are an alternative version of the Sonora Bobcat models (Marley et al. 2021) with updated molecular line lists (see Table 4 in Tannock et al. 2022a).

The models have two columns:
column 1: vacuum wavelength in microns
column 2: flux in F_lambda units (W/m2/m)

These models have NOT been smoothed for rotation, shifted for RV, resampled to the IGRINS wavelengths, or otherwise altered.
