The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

We present near-infrared (1 to 2.5 micron) low-resolution spectroscopy of eleven ultracool dwarfs with spectral types ranging from M7 to L8. Combining our observations with data published previously by Leggett et al. (2001), we have measured equivalent widths for the strongest atomic features and constructed narrowband indices to gauge the strength of the strongest molecular features. Those measurements show that the behaviourr at near-infrared wavelengths is well correlated with spectral type, where the latter is defined from observations between 6300 and 10000 Angstroms.

Original abstract

We present near-infrared (1 to 2.5 micron) low-resolution spectroscopy of eleven ultracool dwarfs with spectral types ranging from M7 to L8. Combining our observations with data published previously by Leggett et al. (2001), we have measured equivalent widths for the strongest atomic features and constructed narrowband indices to gauge the strength of the strongest molecular features. Those measurements show that the behaviourr at near-infrared wavelengths is well correlated with spectral type, where the latter is defined from observations between 6300 and 10000 Angstroms. In particular, four indices designed to measure absorption in the wings of the 1.4 and 1.85 micron steam bands exhibit a linear, monotonic correlation with spectral type on the Kirkpatrick et al. (1999) system, allowing consistent calibration from both optical and near-infrared spectroscopy.
