SpeX NIR spectra and extinction curves

SpeX near-infrared spectra and measured extinction curves for a sample of Milky Way sightlines.

SpeX_spectra.zip contains the SpeX near-infrared spectra of 15 comparison and 25 reddened O/B type Milky Way stars, that were used to measure extinction curves.

Data_files.zip contains the data files of the stars in the format required by the code.

Ext_curves.zip contains 15 measured extinction curves and the measured average diffuse Milky Way extinction curve.

See our paper Decleir et al. (ApJ, submitted) for a detailed discussion of our method and results.

See the associated spex_nir_extinction GitHub repository (Decleir et al. 2021) for the code, Tables and Figures.

This version (2.0) is an update from the first version (1.0), and is associated with the revised version of the paper. Changes include:

updated uncertainties for R(V) in the headers of the extinction curve fits files.

addition of 1/R(V) in the headers of the extinction curve fits files.

addition of comments in the data files about the references and quality of the photometry
