Additional tables of southern spectrophotometric standards are available in /midas/calib/data/spec/ctio (Hamuy & al., 1992, PASP, <B>104</B> 533-552 and Hamuy & al., 1994, PASP <B>106</B> 566-589) and midas/calib/data/datatrans/hststd (HST Standards). <P> These tables are distributed on request in complement to the Midas releases. These tables are also available on anonymous ftp at the host <B>ftphost.hq.eso.org</B> (IP number 134.171.40.2). The files to be retrieved are located in the directory /midaspub/calib and are named README.calib and calib.tar.Z. Command <TT>SHOW/TABLE</TT> can be used to visualize the column name and physical units of the tables. Demonstration data required to execute the tutorial procedure <TT>TUTORIAL/ECHELLE</TT> are also located on this ftp server in the directory /midaspub/demo as echelle.tar.Z.
