The Stony Brook/SMARTS Spectral Standards Library
As a part of the SMARTS spectroscopic observing program, I have been amassing
a series of observations of mostly-southern spectroscopic standard stars.
These are all
bright stars, and are usually observed in twilight, as fillers at the
beginnings and ends of the night, or through clouds when the primary
observing program would be seriously compromised.
The following tables list all the standards we have observed to date.
It will be updated as appropriate.
Standards and
their spectral types have been gleaned from a number of sources.
For each grating setup, we provide a gif image and the fits file containing
the reduced data. The data have been reduced by our IDL pipeline.
Details about the format of the fits file are provided
here. The plots are of the first
vector in the file, the boxcar extracted, flux-corrected spectrum.
Note that the fluxes are not absolute, since this is A.) slit spectroscopy, and
B.) many of the spectra were obtained under less-than-ideal conditions.
The purpose of the calibration is to remove the instrumental response and
approximate the true continuum shape. However, there may be low frequency
features in the continuum, and the continuum shapes near the ends of the
spectral range can be untrustworthy.
These artifacts result from the polynomial
fitting of the photometric standard star data.
All the fits files are available in
this gzipped tar file.
Individual files are named using the designation in the first column of the
table. The file size is currently 16.4 MB.
