DIGITIZED SPECTRA DATA

There are many online databases of digitized spectra of stellar objects at the National Space Science Data Center (NSSDC) available at the Astronomical Data Center's (ADC) Anonymous FTP site. (There are a few other sources as well)

There is a graphics intensive experimental page with various types of plots based on the data from the NASA spectra database.

There is another version of this page with more detailed author information.

I grow daily to honor facts more and more, and theory less and less. A fact, it seems to me, is a great thing - a sentence printed, if not by God, then at least by the Devil.
- Thomas Carlyle: Letter to Emerson, April 29, 1836.
