About the SpeX Prism Library

The SpeX Prism Library is a repository of low-resolution, near-infrared spectra, primarily of low-temperature dwarf stars and brown dwarfs, obtained with the SpeX spectrograph mounted on the 3m NASA Infrared Telescope Facility on Mauna Kea, Hawaii. The data provided here have been obtained using the prism-dispersed mode of SpeX with resolutions of 75-200 and spectra spanning 0.65-2.55 microns in a single order. All data have been uniformly reduced using Mike Cushing's SpeXtool package.

About the SpeX Prism Library Analysis Toolkit

The SpeX Prism Library Analysis Toolkit (SPLAT) is a python-based spectral access and analysis package designed to interface with the SpeX Prism Library. It is built on common python packages such as astropy, numpy, scipy, and matplotlib, among others.
