New Solar Atlas for the Thermal Infrared...(1Sep94)
(8 to 21 um) (from NSO, NOAO Newsletter No. 39, 1 September 1994)

"An Atlas of the Sunspot Spectrum from 470 to 1233 cm^-1 (8.1 to 21 um) and
the Photospheric Spectrum from 460 to 630 cm^-1 (16 to 22 um)" is now
available. Lloyd Wallace, with help from Peter Bernath, has prepared this,
which is yet another IR atlas based on the FTS archives. The umbral component
is especially rich in SiO and H2O. Some 2550 lines of the former and 2047 of
the latter are identified. From the SiO lines the temperature of the spot
umbra is estimated to be 3200 K, corresponding roughly to spectral class M4V.
Other solar lines include a couple hundred of OH, the Mg 530.99 cm^-1, and H
524.61 cm^-1.

Other atlases of the series are: "An Atlas of the Photospheric Spectrum from
8900 to 13600 cm^-1 (7350 to 11230 )," "An Atlas of the Solar Spectrum in
the Infrared from 1850 to 9000 cm^-1 (1.1 to 5.4 um)," and "An Atlas of a
Dark Sunspot Umbral Spectrum from 1970 to 8640 cm^-1 (1.16 to 5.1 um)."
Interested workers may obtain copies free of charge from NSO/Tucson.
