Spectral data

Jouni Haanpalo, <>, has measured spectral data from many objects. He made this data available at an ftp site, but the files are apparently unavailable (at 1999-05-23). He had a web page, but at 1999-05-23 the page is apparently unavailable. I have not been in touch with him; it seems he's left the university.

The remainder of this page provides links to the original files, at their original locations. They are not copied or available at my site.

The files are available in ASCII text format (Gzip compressed), and MatLab format (Gzip compressed). Some are tar'd. You can find information about document formats. All of the links here access Haanpalo's ftp server.

On the other hand, you might try to access the LUT pages directly.
