Abstract:
An Atlas of 115 medium-resolution K-band (2.0-2.4um) stellar spectra,
spanning spectral types O-M and luminosity types I-V, is presented.
K-band spectra are also presented for one N- and one J-type carbon
star. A time series of spectra is presented for an S-type Mira
variable. All the spectra are at a resolution of ∼3000 (1.4cm-1) and
have had the terrestrial absorption removed by dividing a featureless
spectrum. The spectra are plotted with the major spectral features
identified and are available digitally.

Note on Freq:
The frequency scale where all stars have been interpolated onto a
scale from 4150.0 to 4950.0cm-1 at intervals of 0.5cm-1.
Note on FiltSum:
The fully processed version of the spectrum described in section
3 of the printed paper.
Note on FiltDiff:
The fully processed difference of the forward and backward scans,
which gives an objective measure of the S/N in the processed spectrum.
Note on UnfiltSum:
A version of the spectrum which is processed but not filtered.
Specifically, the notch filter designed to remove the 3.4cm-1/cycle
ringing and the apodizing filter were not applied. This version is
included because for some purposes less filtering can clarify some
questions.
