Alkim: I have prepared data for the remaining ut's, i.e., 0-3 and 18-24. ut 24 is actually ut 0 of the next model day. So you should now have a complete set of 25 uts from 0 to 24. The file is on hao.hao.ucar.edu in /pub/foster, file name is alkimdat.tar.Z. Format, etc, is same as before. Sorry this took so long. --Ben ----------------------------------------------------------------------- Ben Foster High Altitude Observatory (HAO) foster@ncar.ucar.edu phone: 303-497-1595 fax: 303-497-1589 Nat.
