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).<br> <br> All files are text files. Header information is marked with a '#' at the start of the line.<br> <br> 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.<br> <br> The IGRINS data files have four columns:<br> column 1: vacuum wavelength in microns<br> column 2: flux in normalized F_lambda units<br> column 3: uncertainty on the flux<br> column 4: signal-to-noise ratio<br> <br> <br> 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.<br> <br> <br> 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).<br> <br> The models have two columns:<br> column 1: vacuum wavelength in microns<br> column 2: flux in F_lambda units (W/m2/m)<br> <br> These models have NOT been smoothed for rotation, shifted for RV, resampled to the IGRINS wavelengths, or otherwise altered.本数据集收录了T6型矮星2MASS J08173001-6155158的双子座南（Gemini South）望远镜/IGRINS光谱数据，以及两套Sonora Bobcat Alternative A模型光谱，相关内容出自Tannock等人2022a的研究（该工作于2022年1月提交至《皇家天文学会月报》（MNRAS））。 所有文件均为文本文件，文件头部行首以字符'#'标记注释信息。 H与K波段的IGRINS每个光谱阶（各阶的波长覆盖范围详见Tannock等人2022a的表2）均对应一个独立数据文件，同时H、K波段各配有一个光谱阶拼接文件。单光谱阶数据已归一化至单位1，拼接文件则归一化至峰值为单位1。 IGRINS数据文件包含四列数据：第1列为真空波长（单位：微米）；第2列为归一化F_λ单位下的流量；第3列为流量的不确定度；第4列为信噪比。 该光谱已完成大气校正（通过将科学光谱除以A0V型星的光谱实现），且为三次观测时段的加权平均结果。本数据集未包含Tannock等人2022中提及的仪器系统误差二次校正项。 模型光谱为Callie Hood生成的Sonora Bobcat Alternative A模型（Hood等人待发表）。该模型是Sonora Bobcat模型（Marley等人2021）的变体版本，更新了分子线表（详细信息参见Tannock等人2022a的表4）。 模型光谱文件包含两列数据：第1列为真空波长（单位：微米）；第2列为F_λ单位（W/m²/m）下的流量。 本模型光谱未针对自转展宽进行平滑处理、未进行径向速度（RV）位移校正、未重采样至IGRINS的波长尺度，也未进行其他修改操作。
