HPOL RED-nearIR SPECTRA
The following is a list of the spectrum standard
The header on a standard star plot will give the star name
(or names), spectral type, and usually the catalog in which
it appears as a standard, and date of observation.
These spectra all have Earth atmosphere absorption features, so are
less useful for classification than the shorter wavelength spectra.
They are given here for comparison.
Not all the blue wavelength spectrum standard stars in that
directory have a red spectrum here.
Some of these standards have emission at Halpha.

Alpha Her AB M5Ib-II Alpha Her is a binary; the spectral type
refers to the primary; the secondary is a G giant a few arc seconds away which also lies in the HPOL
Component B is about 2 mag fainter than A; the spectrum should be dominated by
A at these wavelengths.
