Using the Libraries

The data provided here are being made available to facilitate research on very low mass stars and brown dwarfs, to reduce the occurrence of unnecessarily repeated observations, and to facilitate collaboration.

The data present here are technically copyright protected by the authors and journal publishers. So please be sure to cite the original data reference(s) when presenting these data in publication or in a talk.

The libraries are basically lists of sources for which SpeX prism spectra have been obtained. For source we have listed the name, 2MASS designation (sexigesimal coordinates in the form hhmmss[.]ss+ddmmss[.]s), optical and near-infrared spectral types, and 2MASS J magnitude, as collated from DwarfArchives.org or the literature. Click on the designation name for images of each source field from IRSA's FinderChart program.

Following that are spectral information, including spectral resolution, observation date and links to the ascii data files (if published), jpeg plots for visualization, and the data source citation (with cross-reference to NASA ADS). Data of poor quality are highlighted in red. A zip archive of all published data in each library are provided, as well as a celestial map of the sources.

If there are additional capabilities you would like to see with these libraries, please email your suggestions to aburgasser AT gmail DOT com.
