The regional servers for GRT logs are shown in Table 8. Many are the same as the server for schedule files, but there are some differences in both the server used and/or the subdirectory used. IP addresses for these FTP sites are given in Table 2 The sub-directory containing the logs on most servers is of the form mmmyy, where mmmyy is the month and year of the start date (UTC) of the observation, e.g. sep97. The NRAO AOC site introduced the pppppp (observation code) sub-directory structure in 1998: see section 10.2.5 for more details.
