The two programs you need are: If you are brave, you can try to use the newer version of equiv.pro that I edited. At the IDL prompt, type: .run equiv_2003.pro, however, to run the program, you still type "equiv,wave,flux,x1,x2,'w'". I also revised pixel.pro. Again, I did not change much, however, it may be a bit more robust than the older version. Same instructions apply: .run pixel_2003.pro compiles it, but you still type "pixel,wave,flux" to run the program. If you have problems with either of the new codes, please report them to me. If you don't trust the new code, please continue to use the original versions. Also, you will need the standard star spectra. There are 25 of these, so in order to simplify the download of these files, I have written all of the files into a compressed archive, called a "tar" file. After you download the archive from this webpage, type "gunzip stars.tar.gz" at a UNIX prompt in a terminal window to uncompress the file. Then, type "tar -xvf stars.tar" to separate the individual files from the archive. Once this is done, you can remove the tar file by typing, "rm stars.tar".
