Yes, I have found the memo at www ander <documentation>. But the DOCUMENTATION title says that The most recent AIPS Memo is number 103 That confused me. DOCUMENTATION AIPS Memos, Reports, old AIPSLetters, the Cookbook, Going AIPS, access to the newest versions of the HELP files, search CHANGE.DOC and more. The most recent AIPS Memo is number 103 ^^^ Leonia
